It occupies the small Qatar Peninsula on the northeastern coast of the Arabian Peninsula, and shares its sole land border with neighbouring Gulf Cooperation Council monarchy Saudi Arabia to the south, with the rest of its territory surrounded by the Persian Gulf. The Gulf of Bahrain, an inlet of the Persian Gulf, separates Qatar from nearby Bahrain. The capital is Doha, home to over 80% of the nation's population.

In early 2017, Qatar's total population was 2.6 million: 313,000 Qatari citizens and 2.3 million expatriates. Its official religion is Islam. In terms of income, the country has the fourth-highest GDP (PPP) per capita in the world, and the sixth-highest GNI per capita (Atlas method). Qatar is classified by the United Nations as a country of very high human development, having the third-highest HDI in the Arab world. It is a high-income economy, backed by the world's third-largest natural gas reserves and oil reserves. Qatar is the world's largest exporter of liquefied natural gas, and the world's largest emitter of carbon dioxide per capita.Qatar has been ruled by the House of Thani since Mohammed bin Thani signed a treaty with the British in 1868 that recognised its separate status. Following Ottoman rule, Qatar became a British protectorate in the early 20th century until gaining independence in 1971. The hereditary emir of Qatar rules as an autocrat (currently, Tamim bin Hamad Al Thani) and holds all executive and legislative authority, as well as controlling the judiciary. He appoints the prime minister and cabinet.In the 21st century, Qatar emerged as a significant power in the Arab world through its resource-wealth, as well as its globally expanding media group, Al Jazeera Media Network, and reportedly supporting several rebel groups financially during the Arab Spring. For its size, Qatar wields disproportionate influence in the world, and has been identified as a middle power. The 2022 FIFA World Cup will be held in Qatar, making it the first Muslim and Arab country to host the event. The 2030 Asian Games will also be held in Qatar.
