Ukraine was known as “Kievan Rus” (from which Russia is a derivative) up until the 16th century. In the 9th century, Kiev was the major political and cultural center in eastern Europe. Kievan Rus reached the height of its power in the 10th century and adopted Byzantine Christianity, the Church Slavonic written language, and the Cyrillic alphabet during that period. The Mongol conquest in 1240 ended Kievan power. From the 13th to the 16th century, Kiev was under the influence of Poland and western Europe. The negotiation of the Union of Brest-Litovsk in 1596 divided the Ukrainians into Orthodox and Ukrainian Catholic faithful. In 1654, Ukraine asked the czar of Moscovy for protection against Poland, and the Treaty of Pereyasav signed that year recognized the suzerainty of Moscow. The agreement was interpreted by Moscow as an invitation to take over Kiev, and the Ukrainian state was eventually absorbed into the Russian empire.
After the Russian Revolution, Ukraine declared its independence from Russia on Jan. 28, 1918, and several years of warfare ensued with several groups. The Red Army finally was victorious over Kiev, and in 1920 Ukraine became a Soviet republic. In 1922, Ukraine became one of the founders of the Union of Soviet Socialist Republics. In the 1930s, the Soviet government's enforcement of collectivization met with peasant resistance, which in turn prompted the confiscation of grain from Ukrainian farmers by Soviet authorities; the resulting famine took an estimated 5 million lives. Ukraine was one of the most devastated Soviet republics after World War II. (For details on World War II, see Headline History, World War II.) On April 26, 1986, the nation's nuclear power plant at Chernobyl was the site of the world's worst nuclear accident. On Oct. 29, 1991, the Ukrainian Parliament voted to shut down the reactor within two years' time and asked for international assistance in dismantling it.
When President Leonid Kravchuk was elected by the Ukrainian Parliament in 1990, he vowed to seek Ukrainian sovereignty. Ukraine declared its independence on Aug. 24, 1991. In Dec. 1991, Ukrainian, Russian, and Belorussian leaders cofounded a new Commonwealth of Independent States with the new capital to be situated in Minsk, Belarus. The new country's government was slow to reform the Soviet-era state-run economy, which was plagued by declining production, rising inflation, and widespread unemployment in the years following independence. The U.S. announced in Jan. 1994 that an agreement had been reached with Russia and Ukraine for the destruction of Ukraine's entire nuclear arsenal. In Oct. 1994, Ukraine began a program of economic liberalization and moved to reestablish central authority over Crimea. In 1995, Crimea's separatist leader was removed and the Crimean constitution revoked.
In June 1996, the last strategic nuclear warhead was removed to Russia. Also that month Parliament approved a new constitution that allowed for private ownership of land. An agreement was signed in May 1997 on the future of the Black Sea fleet, by which Ukrainian and Russian ships will share the port of Sevastopol for 20 years.
The Russian financial crisis in fall 1998 led to severe problems for the Ukrainian economy, which is dependent on Russia for 40% of its foreign trade. Ukraine remains saddled with its Soviet-era economy, and most of its major industries are still under state control. Corruption is rampant, and as a result, Western investors have shown only minimal interest. The election of the reform-minded Viktor Yushchenko as prime minister in Dec. 1999, however, was greeted with optimism by the West. He was also highly popular among Ukrainians. But in April 2001, he was dismissed in a no-confidence vote engineered by Communist hardliners and Ukrainian big business.
In the winter of 2001 violent demonstrations rocked Ukraine, with protesters demanding the resignation and impeachment of authoritarian president Leonid Kuchma. Critics accused Kuchma of involvement in the murder of a journalist critical of government corruption. Kuchma was recorded on tape urging that the journalist be disposed of.
In 2004, Kuchma announced he would be retiring. A presidential election on Oct. 31, 2004, pitted Viktor Yushchenko, the former reformist prime minister, against Viktor Yanukovich, the current prime minister and Kuchma's choice. The campaign was an especially dirty one. Yushchenko was allegedly poisoned and had to be hospitalized for several weeks shortly before the election. Yanukovych won 40% of the vote against Yushchenko's 39%; a runoff will be held on Nov. 21.
