On September 22, 1908, Prince Ferdinand (1861-1948) of Bulgaria declared the country’s independence from the Turkish Ottoman Empire, which had ruled since the 14th century. In 1944, the former Soviet Union invaded Bulgaria and imposed its communist system for nearly 50 years. Like many other eastern European countries, Bulgaria became an independent republic with a new constitution in 1991. In 1998, the Bulgarian Parliament reinstituted September 22 as Bulgarian Independence Day. Discuss
