Ukraine

Ukraine,  Україна or Ukraina, is a country in eastern Europe on the Black Sea.
 * After being part of Russia for many years, Ukraine became independent in 1918 as Українська Народна Республіка (Ukrainian People's Republic) following the February Revolution in Russia. It issued a definitive series with Russian stamps still accepted for postage.
 * However, it became necessary to differentiate legitimate postage stocks from imports, so trident overprints of many types were applied. Various local overprints were necessary because of the ongoing civil war. To add to the confusion, there are many fakes and forgeries of the trident overprints.
 * During 1920-22, hyperinflation made it necessary to overprint Russian stamps including those with trident overprints with a РУЪ. overprint that converted kopeck value stamp into ruble values.
 * By 1922, Ukraine was once again part of Russia in the new Soviet Union.
 * During 1941-43, Ukraine was occupied by Germany and used German stamps overprinted UKRAINE. See: UKRAINE (overprint).
 * In December 1991, the Soviet Union was dissolved and Ukraine became an independent nation. Its first stamp appeared in March 1992.

Bogus issues
There have been bogus issues attributed to Ukraine in the early part of the 20th Century. In the early 1990s, bogus stamps were created by overprinting various Soviet definitives singly and in blocks, with the Ukrainian trident symbol. Sheetlets and souvenir sheets followed for a time. These have been supposedly attributed to the cities of Odessa and Vinnytsia. Recent bogus issues for Crimea also exist.
