The network of railroads and highways had to be adjusted to the new shape of the republic, which stretched from the Cheb (Eger) region in western Bohemia to the Carpathians in the east. The new country's first minister of finance, Alois Rašín, saved the Czechoslovak currency from catastrophic inflation, and his death in February 1923, after he was shot by a young revolutionary, was a shock to the new republic. In the chaotic conditions prevailing in central Europe after the armistice, a parliamentary election appeared to be impossible. The Czech and Slovak leaders agreed on the composition of the National Assembly. The Assembly's main function was the drafting of a constitution. The new, democratic constitution was adopted on Feb. 29, 1920, and was modeled largely on that of the French Third Republic. Supreme power was vested in a bicameral National Assembly. The Chamber of Deputies and the Senate had the right to elect, in a joint session, the president of the republic for a term of seven years. The Cabinet was made responsible to the Assembly. Fundamental rights of the citizens, irrespective of ethnic origin, religion, and social status, were defined generously. Some parties, however, saw a contradiction between the constitutional guarantee of equal rights for all citizens and the intention to create a state of the Czechs and Slovaks. Large segments of the population gave wholehearted support to the republic; the most resolute opposition, however, came from an ethnic minority that soon came to be known as the Sudeten Germans. The age-old antagonism between Germans and Slavs, accentuated during the war, prevented cooperation during the opening stages of the republic. The Germans issued protests against the constitution but participated, nevertheless, in parliamentary and other elections. In 1925 two German parties—the Agrarian and Christian Socialist—joined the government majority, thus breaking a deadlock. Disagreement with the trend toward centralism was the main source of dissatisfaction among the Slovak Populists, a clerical party headed by Andrej Hlinka. Calls for Slovak autonomy were counterbalanced by other parties seeking closer contacts with the corresponding Czech groups; the most significant contribution to that effort was made by the Agrarians under Milan Hodza and by the Social Democrats under Ivan Dérer. The strongest single party in the opening period, the Social Democracy, was split in 1920 by internal struggles; in 1921 its left wing constituted itself as the Czechoslovak section of the Comintern. After the separation of the communists, the Social Democracy yielded primacy to the Agrarians.
