The European Union (EU) is a political and economic union of 27 member states that are located primarily in Europe. Its members have a combined area of 4,233,255.3km2 (1,634,469.0sqmi) and an estimated total population of about 447million. The EU has developed an internal single market through a standardised system of laws that apply in all member states in those matters, and only those matters, where members have agreed to act as one. EU policies aim to ensure the free movement of people, goods, services and capital within the internal market; enact legislation in justice and home affairs; and maintain common policies on trade, agriculture, fisheries and regional development. Passport controls have been abolished for travel within the Schengen Area. A monetary union was established in 1999, coming into full force in 2002, and is composed of 19 EU member states which use the euro currency. The EU has often been described as a sui generis political entity (without precedent or comparison).
Zagreb is the capital and the largest city of the Croatia. It is located in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb lies at an elevation of approximately 122 m above sea level. In the census of 2011 the population of the city was 790,017.
Zagreb is a city with a rich history dating from the Roman times to the present day. The oldest settlement in the urban area of the city is Andautonia, a Roman settlement in the place of today's Ščitarjevo. The name "Zagreb" is mentioned for the first time in 1094 at the founding of the Zagreb diocese of Kaptol, and Zagreb became a free royal town in 1242, whereas the origin of the name still remains a mystery in spite of several theories. In 1851 Zagreb had its first mayor, Janko Kamauf, and in 1945 it was made the capital of Croatia when the demographic boom and the urban sprawl made the city it's known nowadays.
