Stresemann was the son of Ernst Stresemann, a Berlin innkeeper and beer distributor. He was the only one of five children able to attend high school and university. From early childhood he displayed a strong “inclination toward solitude,” as he put it as a student, as well as a tendency to be melancholy and to daydream. At school he displayed an unusual gift for history, especially modern history. He was especially interested in the lives of great personalities, particularly Napoleon (Napoleon I) and Johann Wolfgang von Goethe (Goethe, Johann Wolfgang von), both of whom fascinated him throughout his life and inspired several of his literary studies.

Stresemann, attending the Universities of Berlin and Leipzig from 1897 to 1900, first studied literature and history but changed to economics, probably to improve his professional prospects rather than in recognition of his practical gifts. While a student he belonged to a relatively progressive fraternity and retained a lifelong attachment to the sentimental glories of student life. In 1900 he received his doctorate with a dissertation entitled “The Growth of the Berlin Bottled-Beer Industry.” The subject of his study, based on his knowledge of his father's business and dealing with the decline of a sector of small business as a result of competition from giant industry, was characteristic of his origins as well as of his point of view. It was used against him in future political struggles by right-wing opposition.

As a liberal Prussian Protestant, Stresemann became a typical representative of the chauvinistic spirit prevailing in imperial Germany. He believed in the spiritual, military, and economic superiority of the German Empire, and his political idealism (nationalism) manifested itself in a sentimental enthusiasm for the heroic liberalism of the revolutions of 1848 (1848, Revolutions of), as well as in a romantic style of speech.

After completing his studies, Stresemann began his professional career in a trade association. Unusually rapid success in commerce gave him a springboard into politics. As an administrative assistant in the German Chocolate Makers' Association from 1901 to 1904, he gained a reputation as an accomplished organizer and negotiator. By 1902 he had founded the Saxon Manufacturers' Association, and as its legal representative until 1911, he occupied an important position in economic life at the age of 25.

His wife, whom he married in 1903, was the sister of a fraternity brother and the daughter of the Berlin industrialist Adolf Kleefeld. Of Jewish extraction, Stresemann's charming and elegant wife played a leading role in Berlin society of the 1920s. They had two sons.

After initially sympathizing with the ideas of the Protestant social reformer Friedrich Naumann (Naumann, Friedrich) and collaborating with his National Social Union, Stresemann joined the National Liberal Party in 1903. Strongly represented in Saxony at the time, the party became Stresemann's political home. Often involved in conflicts over his support of social-welfare measures with the right wing of his party (which was dominated by representatives of heavy industry), he attracted general notice at his first appearance at a party congress in 1906.

As a Dresden city councillor from 1906 to 1912 and editor of the Dresden magazine Sächsische Industrie (“Saxon Industry”), Stresemann became a well-known writer on economics and an expert on municipal affairs. Recognizing the importance of the press in influencing public opinion, he took advantage of it to support his aims.

He was elected in 1907 to the Reichstag (parliament) as a National Liberal from the Annaberg district in the Saxon metal-mining country, thus gaining a foothold in national politics. At 28 he was the youngest deputy in the Reichstag. The party chairman, Ernst Bassermann (Bassermann, Ernst), helped to advance his political career, and Stresemann was soon considered Bassermann's “crown prince.” Stresemann was primarily interested in economic policy both as a journalist and a deputy. He energetically defended the interests of the commercial middle class, but his advocacy of extended social-welfare legislation embroiled him in a conflict with the representatives of his party's right wing, which in 1912 prevented his reelection to the National Liberal Party executive committee. After losing his seat in the new Reichstag elections in the same year, he traveled with other business leaders to the United States to study economic conditions.

By this time Stresemann, who had moved to Berlin, was one of the best-known leaders of German economic life. He occupied leading positions in a number of trade associations, including the German-American Economic Association, established at his suggestion. Stresemann's many offices brought him financial independence. He was known for his organizational gifts, knew how to handle people, and was aware of the power he wielded. As a member of the pan-German (Pan-Germanism) Deutscher Kolonialverein (German Colonial League) and an advocate of a strong naval construction program, he supported the imperialist goals of German policy carried out under the aegis of Alfred von Tirpitz (Tirpitz, Alfred von) and Bernhard, Fürst (prince) von Bülow (Bülow, Bernhard, Fürst von). Tirpitz had served as state secretary of the Imperial Naval Office, in which post he created the German battle fleet, and Bülow was chancellor of Germany (1900–1909).

Stresemann was a part of the great majority of Germans who, in the firm belief that Germany was conducting a purely defensive war, greeted the outbreak of World War I with enthusiasm. Because of his poor health he was exempted from military service. His political hour struck, however, in December 1914, when he was returned to the Reichstag in a special election.

Stresemann emerged during the war as one of the most vociferous exponents of Pan-Germanism and as a champion of Germany's extensive claims on Polish and Russian territory in the east and on French and Belgian territory in the west. He virtually took over leadership of his party's Reichstag faction from Bassermann, whom military service and illness kept away from Berlin much of the time. During these years Stresemann moved increasingly to the right. From 1916 he worked closely with the German Army Supreme Command under Field Marshal Paul von Hindenburg (Hindenburg, Paul von) and General Erich Ludendorff (Ludendorff, Erich) and became their parliamentary mouthpiece. He advocated unrestricted U-boat warfare and opposed the policy of Chancellor Theobald von Bethmann Hollweg (Bethmann Hollweg, Theobald von), who held to a moderate course and did not allow himself to be committed to expansionist war aims.

Stresemann played a leading role in Bethmann Hollweg's overthrow in July 1917 but failed to bring back to power the former chancellor Bülow, whom he admired. After Bassermann's death in the same month, Stresemann succeeded him as leader of the party's Reichstag faction, becoming chairman of the entire party later in the same year. Despite radical differences within the National Liberal ranks, Stresemann was able to prevent a party split between the Reichstag faction and its more conservative counterpart in the Prussian House of Deputies over the Prussian three-class suffrage system, in which a citizen's vote was weighted according to the value of his property. Hoping to strengthen the monarchy, Stresemann advocated abolition of the voting system. On the other hand, he allowed himself to be deceived about the seriousness of the military situation of the Reich and its allies until the Supreme Command admitted defeat at the end of September 1918.

The defeat, the collapse of the monarchy on November 9, 1918, and the flight of Emperor William (Wilhelm) II (William II) to Holland were cruel blows to Stresemann. Nonetheless, he quickly accommodated himself to the realities of a republican Germany. However, when the newly formed left-liberal German Democratic Party, led by Naumann (Naumann, Friedrich) and the renowned sociologist Max Weber (Weber, Max), refused to admit him to its higher councils, Stresemann founded his own party, the German People's Party. A right-liberal grouping of educated and propertied elements, it sought to rally the right-wing supporters of the former National Liberal Party. Stresemann, fundamentally a monarchist and an opponent of the Weimar Republic, assumed an ambiguous “wait-and-see” attitude during the rightist Kapp Putsch of March 1920. When the putsch was suppressed, however, he prepared to cooperate politically with the republic. He tried to persuade the democratic parties that the German People's Party was qualified to participate in a coalition and pressed for a position in the government. For the time being, however, he was still counted among the “national opposition” to the Weimar coalition—the Social Democratic Party (Social Democratic Party of Germany), the German Democratic Party, and the Centre Party.

Stresemann, a member of the German National Constituent Assembly in Weimar in 1919–20, was an opponent of the new German constitution. He also opposed the Treaty of Versailles (Versailles, Treaty of) and was to devote his political life to its revision. From 1920 until his death Stresemann was a Reichstag deputy and chairman of the German People's Party, and in August 1923 he became chancellor of the Reich at the head of a “Great Coalition,” composed of representatives of the Social Democrats, the Centre, and the German Democrats, as well as of his People's Party.

As chancellor from August 13 to November 23, 1923, during the crisis over the Allied occupation of the Ruhr, and as foreign minister from August 1923 to his death, Stresemann exercised decisive influence over the fate of the Weimar Republic, and he became a statesman of European stature. His first decision as chancellor was to abandon the policy of passive resistance in the Ruhr, which in January 1923 had been occupied by French and Belgian troops to enforce payment of German war reparations. This policy had accelerated inflation and was precipitating a financial collapse.

On the domestic scene, he sought to steer his way among opposing domestic forces. While proceeding harshly against communist-influenced state governments in Thuringia and Saxony, he displayed a lenient attitude toward revolutionary attempts of the radical right, such as the Beer Hall Putsch of Adolf Hitler (Hitler, Adolf) on November 8–9, 1923, in Munich (Beer Hall Putsch). At the height of the internal political crisis of November 1923 there was danger that the occupied territory west of the Rhine (Rhineland) (occupied by the Allies) might withdraw from the Reich. Only the stabilization of the currency in the middle of November—the last significant achievement of Stresemann's government—restored domestic order and created the basis for economic recovery.

Overthrown by a vote of no confidence, the cabinet resigned in November 1923. Stresemann took over the post of foreign minister in the new government and held it, unchallenged until his death, in coalition governments of varying composition under three chancellors ranging from the left to centre. His policy was aimed at securing a reconciliation with the victorious Western powers, especially France, for Germany had already renewed ties with Russia (Union of Soviet Socialist Republics) through the Treaty of Rapallo in 1922. By meeting the reparation payments, for the reduction of which he fought as stubbornly as he did for removal of French troops from west of the Rhine, he hoped to gain a favourable position for his negotiations with the victorious Allies. His enduring aim was to obtain equal rights for Germany and to restore it to its former position among the countries of Europe.

Principally, however, this meant a revision of Germany's eastern border of 1919, which would require Poland to return Danzig, the Polish Corridor, and Upper Silesia, as well as the annexation of Austria. Realistically appraising Germany's central position in Europe and exploiting Anglo-French and Anglo-Soviet tensions, Stresemann tried to achieve his goals through negotiation, but his seesaw policy between East and West was strongly criticized by many contemporary critics. Yet Stresemann retained his optimism, often carrying it to extremes, and this outlook frequently led him to underestimate opposition both at home and abroad.

Stresemann's successes in dealing with the Allied powers during those years can be marked out in stages. In 1924 the U.S.-proposed Dawes Plan was signed, providing for reduction in payment of reparations and stabilization of German finances. It was followed in 1925 by the Pact of Locarno (Locarno, Pact of), which included acceptance of the new Franco-German border, agreements to arbitrate disputes with other nations, and immunity from new sanctions by the victors of World War I.

In 1926 the first Rhineland zone was evacuated by the Allies, Germany was admitted to the League of Nations (Nations, League of), and the Berlin Treaty with the Soviet Union (an agreement providing for mutual neutrality) was signed. In 1928 the Kellogg-Briand Pact outlawing war was signed by Germany. Stresemann did not live to see the complete evacuation of French troops from the Rhineland and the completion of the new settlement reducing German reparations through the Young Plan (also a U.S. proposal) in 1929, although he had conducted the negotiations when already marked by death.

Any summary of Stresemann's diplomatic successes should not obscure the fact that he devoted an extraordinary amount of effort to combating strong domestic opposition that arose, above all, from his own party. Stresemann, who took the importance of the press into consideration, used publicity to promote his policy but, by making premature statements, often aroused political hopes that could not be realized. After his spectacular secret meeting in 1926 with Briand—which gave rise to exaggerated hopes—Franco-German rapprochement came to a standstill. In the last two years of his life, which were marked by illness, Stresemann became increasingly dissatisfied at his failure to further his foreign policy, especially after his party dwindled and large sections of it went over to the extreme right. He himself contemplated formation of a new party of the liberal centre. The domestic struggle in particular weakened his already precarious health, and he died after suffering two strokes, at the age of 51.

By virtue of his six years of service as foreign minister and the esteem he enjoyed, particularly abroad, Stresemann made an essential contribution to securing the Weimar Republic's stability and survival for a few years. Because of domestic undercurrents and opposition, he succeeded at the cost of extraordinary personal effort.

On his death, the republic, which honoured him with a state funeral, lost one of its few statesmen. In his personal as well as his political development he embodied the uncertainty of the period of transition from monarchy to republic. Yet he was unable to integrate his own party, over which he jealously maintained leadership, into the Weimar state and thus failed, as he wrote in 1929, to form the bridge “between the old and the new Germany.”

As an advocate of a “policy of national realism,” as opposed to a “pacifist policy of resignation,” he was by no means a champion of European unification. He supported its objectives, however, since he could thus more easily obtain the urgently sought revision of the Treaty of Versailles.

Stresemann's image is still controversial. He was first pronounced a hero after 1945, when he was viewed as a champion of a united Europe. This view was succeeded in the 1950s by an increasingly critical evaluation, especially during the disclosure of his voluminous literary estate, which was at first exclusively at the disposal of U.S. historians. He was then portrayed as a flexible and opportunistic politician of nationalistic sympathies who shrewdly adjusted his aims to meet the needs of the time, and it was said that Stresemann had not become a democrat out of conviction but rather that he had raised “finessing” to the level of a principle. His volatile character and sentimental attachment to uniforms and tradition were also emphasized. The communists, meanwhile, regarded him as a representative of monopoly capitalism and a forerunner of Hitler.

More recently, he has been characterized as a “pragmatic conservative” who remained flexible in his choice of political means while pursuing his national aims of restoration of German wealth and power and the continuation of German traditional social and economic order. Others have emphasized the European aspect of the German “patriot” Stresemann, a viewpoint from which German historical research has departed. Yet, his political changeability notwithstanding, Stresemann is counted among the few statesmen of his time.
