The country's first big political challenge came in 1924 during an attempted communist takeover. In the depths of a nationwide economic crisis, leaders of the Estonian Communist Party (Eestimaa Kommunistlik Partei--EKP), in close contact with Communist International (Comintern--see Glossary) leaders from Moscow, believed the time was ripe for a workers' revolution to mirror that of the Soviet Union. On the morning of December 1, some 300 party activists moved to take over key government outposts in Tallinn, while expecting workers in the capital to rise up behind them. The effort soon failed, however, and the government quickly regained control. In the aftermath, Estonian political unity got a strong boost, while the communists lost all credibility. Relations with the Soviet Union, which had helped to instigate the coup, deteriorated sharply.
