The politics of Croatia are defined by a parliamentary representative democratic republic framework, where the Prime Minister of Croatia is the head of government, in a multi-party system. Executive power is exercised by the government and the President of Croatia. Legislative power is vested in the Croatian Parliament (Croatian: Sabor). The Judiciary is independent of the executive and the legislature. The parliament adopted the current Constitution of Croatia on 22 December 1990, and decided to declare independence from Yugoslavia. The declaration of independence came into effect on 8 October 1991. The constitution was amended several times since then. The first modern parties in the country developed in the middle of the 19th century, and their agenda and appeal changed reflecting major social changes—breakup of Austria-Hungary and formation of the Kingdom of Serbs, Croats and Slovenes, dictatorship and social upheavals in the kingdom, World War II, establishment of Communist rule and breakup of the SFR Yugoslavia.

Croatia (ⁱ/kroʊˈeɪʃə/ kroh-AY-shə; Croatian: Hrvatska pronounced [xř̩ʋaːtskaː]), officially the Republic of Croatia (Croatian: Republika Hrvatska  listen (help·info)), is a unitary democratic parliamentary republic in Europe at the crossroads of Central Europe, the Balkans, and the Mediterranean. Its capital and largest city is Zagreb. The country is divided into 20 counties and the city of Zagreb. Croatia covers 56,594 square kilometres (21,851 square miles) and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.29 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism.

In the early 7th century the Croats arrived in area of present-day Croatia. They organised the state into two dukedoms by the 9th century. Tomislav became the first king by 925 AD, elevating Croatia to the status of a kingdom. The Kingdom of Croatia retained its sovereignty for nearly two centuries, reaching its peak during the rule of Kings Peter Krešimir IV and Dmitar Zvonimir. Croatia entered a personal union with Hungary in 1102. In 1527, faced with Ottoman conquest the Croatian Parliament elected Ferdinand I of the House of Habsburg to the Croatian throne. In 1918, after World War I, Croatia was included in the short-lived State of Slovenes, Croats, and Serbs that declared independence from Austria–Hungary and co-founded the Kingdom of Yugoslavia. A Croatian state briefly existed during World War II as a fascist puppet state. After the war, Croatia became a founding member and a federal constituent of the Second Yugoslavia, a socialist state. In June 1991, Croatia declared independence, which came into effect on 8 October of the same year. The Croatian War of Independence was fought successfully during the four years following the declaration.

The United States is a federal constitutional republic, in which the President of the United States (the head of state and head of government), Congress, and judiciary share powers reserved to the national government, and the federal government shares sovereignty with the state governments.

The executive branch is headed by the President and is independent of the legislature. Legislative power is vested in the two chambers of Congress, the Senate and the House of Representatives. The judicial branch (or judiciary), composed of the Supreme Court and lower federal courts, exercises judicial power (or judiciary). The judiciary's function is to interpret the United States Constitution and federal laws and regulations. This includes resolving disputes between the executive and legislative branches. The federal government's layout is explained in the Constitution. Two political parties, the Democratic Party and the Republican Party, have dominated American politics since the American Civil War, although other parties have also existed.

Margaret Hilda Thatcher, Baroness Thatcher, LG, OM, PC, FRS, née Roberts (born 13 October 1925) is a British politician and the longest-serving (1979–1990) British prime minister of the 20th century, and the only woman ever to have held the post. A Soviet journalist nicknamed her the "Iron Lady", which later became associated with her uncompromising politics and leadership style. As prime minister, she implemented conservative policies that have come to be known as Thatcherism.

Originally a research chemist before becoming a barrister, Thatcher was elected Member of Parliament (MP) for Finchley in 1959. Edward Heath appointed her Secretary of State for Education and Science in his 1970 government. In 1975 Thatcher defeated Heath in the Conservative Party leadership election and became Leader of the Opposition, as well as the first woman to lead a major political party in the United Kingdom. She became prime minister after winning the 1979 general election.

After entering 10 Downing Street, Thatcher introduced a series of political and economic initiatives to reverse what she perceived as Britain's precipitous national decline. Her political philosophy and economic policies emphasised deregulation (particularly of the financial sector), flexible labour markets, the privatisation of state-owned companies, and reducing the power and influence of trade unions. Thatcher's popularity during her first years in office waned amid recession and high unemployment, until economic recovery and the 1982 Falklands War brought a resurgence of support, resulting in her re-election in 1983. Thatcher was re-elected for a third term in 1987, but her Community Charge (popularly referred to as "poll tax") was widely unpopular and her views on the European Community were not shared by others in her Cabinet. She resigned as Prime Minister and party leader in November 1990, after Michael Heseltine launched a challenge to her leadership.

Nigel Paul Farage ( /ˈfærɑːʒ/, FARR-ahzh; born 3 April 1964, Farnborough, Kent), is a British politician and is the Leader of the UK Independence Party (UKIP), a position he also held from September 2006 to November 2009. He is a Member of the European Parliament for South East England and co-chairs the Eurosceptic Europe of Freedom and Democracy group.

Farage is a founding member of the UKIP, having left the Conservative Party in 1992 after they signed the Maastricht Treaty. Having unsuccessfully campaigned in European and Westminster parliamentary elections for UKIP since 1994, he gained a seat as an MEP for South East England in the 1999 European Parliament Election — the first year the regional list system was used — and was re-elected in 2004 and 2009. Farage describes himself as a libertarian and rejects the notion that he is a conservative.

In September 2006, Farage became the UKIP Leader and led the party through the 2009 European Parliament Election in which it received the second highest share of the popular vote, defeating Labour and the Liberal Democrats with over two million votes. However he stepped down in November 2009 to concentrate on contesting the Speaker John Bercow's seat of Buckingham in the 2010 general election.
