to keep an exclusively anti-Russian treaty [...] Poland wishes to obtain our help in case it were attacked by Germany." Further treaties On March 26, 1926, Poland and Romania signed a Treaty of Alliance to bolster security in Eastern Europe. It was directed against any attack, not just one coming from the Soviet Union. Ratifications were exchanged in Warsaw on February 9, 1927. The treaty was registered in the League of Nations Treaty Series on March 7, 1927. The convention was replaced by the Treaty on Mutual Assistance against Aggression and on Military Aid, signed on February 9, 1927 in Warsaw. In both countries, political changes were taking place. The King of Romania, Ferdinand I died in 1927, leaving the throne to his young grandson, Mihai I. A regency took over the administration of the monarchic institution until the 1930 takeover of Carol II. Relations became colder as their interests diverged. Romania created the Balkan Pact in 1934, together with Yugoslavia, Turkey and Greece. Under the premiership of Gheorghe Tătărescu (1934–1937), Romania's attempt to balance its alliances with Poland and Czechoslovakia was put to the test by a political scandal. Jan Šeba, the Czechoslovak ambassador to Bucharest, published a volume that supported a rapprochement between the Soviet Union and the Little Entente and was prefaced by the Czechoslovak Foreign Minister Kamil Krofta. In early 1937, Krofta denied knowledge of the book's content and, after Tătărescu visited Milan Hodža, his counterpart in Prague, Šeba was recalled. Later that year, Tătărescu met with Polish Foreign Minister Józef Beck in Bucharest. Beck, who had previously opposed the status quo policies of Nicolae Titulescu, unsuccessfully proposed a Romanian withdrawal of its support for Czechoslovakia and an attempt to reach a compromise with Hungary. In 1938, in the wake of the Czechoslovak crisis, Beck urged the Romanian government of Miron Cristea, formed by the National Renaissance Front, to participate at the partition of Czechoslovakia (the Munich Agreement), by supporting Hungary's annexation of Carpathian Ruthenia. He hoped that Hungary's Miklós Horthy would no longer sustain claims over Transylvania. However, the offer was refused by Carol II. As the situation was becoming increasingly volatile in the eve of World War II, the two countries began improving their relations. In 1938, Richard Franasovici, the Romanian ambassador in Warsaw, reported: "[There is] an obvious improvement of Poland's sentiments towards Romania [...]. The main idea here is maintaining, above everything,
