Estonia is the northernmost of the three Baltic states. Surprisingly, the Estonian language is not related to Latvian or Lithuanian, nor is it a Slavic language like Russian. Its only close relative is Finnish, with Hungarian being a more distant relative. Estonia became independent in 1991 when the Soviet Union dissolved, joined the European Union in 2004, and adopted the euro in 2010, the first former Soviet state to do so. Estonia’s economy is heavily dependent on trade. Its largest exports are machinery and electrical equipment, wood and finished wood products, as well as furniture. Freight and passenger transit, especially between Russia and Europe, is also an important part of the economy, and the tourism industry is growing, with the number of visitors to Estonia exceeding the country’s population in most years. Estonia is also a leader in IT and has been called the Silicon Valley of Europe. In 2005, Estonia became the first country in the world to have online voting in a national election.
