Iceland (Icelandic: sland; [istlant] (listen)) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavk, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate.

According to the ancient manuscript Landnmabk, the settlement of Iceland began in 874 AD when the Norwegian chieftain Inglfr Arnarson became the first permanent settler on the island. In the following centuries, Norwegians, and to a lesser extent other Scandinavians, emigrated to Iceland, bringing with them thralls (i.e., slaves or serfs) of Gaelic origin.

The island was governed as an independent commonwealth under the native parliament, the Althing, one of the world's oldest functioning legislative assemblies. Following a period of civil strife, Iceland acceded to Norwegian rule in the 13th century. The establishment of the Kalmar Union in 1397 united the kingdoms of Norway, Denmark, and Sweden. Iceland thus followed Norway's integration into that union, coming under Danish rule after Sweden seceded from the union in 1523. The Danish kingdom forcefully introduced Lutheranism to Iceland in 1550.In the wake of the French Revolution and the Napoleonic Wars, Iceland's struggle for independence took form and culminated in independence in 1918 with the establishment of the Kingdom of Iceland, sharing through a personal union the incumbent monarch of Denmark. During the occupation of Denmark in World War II, Iceland voted overwhelmingly to become a republic in 1944, thus ending the remaining formal ties with Denmark. Although the Althing was suspended from 1799 to 1845, the island republic has been credited with sustaining the world's oldest and longest-running parliament.

Until the 20th century, Iceland relied largely on subsistence fishing and agriculture. Industrialization of the fisheries and Marshall Plan aid following World War II brought prosperity, and Iceland became one of the wealthiest and most developed nations in the world. It became a part of the European Economic Area in 1994; this further diversified the economy into sectors such as finance, biotechnology, and manufacturing.

Iceland has a market economy with relatively low taxes, compared to other OECD countries, as well as the highest trade union membership in the world. It maintains a Nordic social welfare system that provides universal health care and tertiary education for its citizens. Iceland ranks high in democracy and equality indexes, ranking third in the world by median wealth per adult. In 2020, it was ranked as the fourth-most developed country in the world by the United Nations' Human Development Index, and it ranks first on the Global Peace Index. Iceland runs almost completely on renewable energy.

Icelandic culture is founded upon the nation's Scandinavian heritage. Most Icelanders are descendants of Norse and Gaelic settlers. Icelandic, a North Germanic language, is descended from Old West Norse and is closely related to Faroese. The country's cultural heritage includes traditional Icelandic cuisine, Icelandic literature, and medieval sagas. Iceland has the smallest population of any NATO member and is the only one with no standing army, with a lightly armed coast guard.

Afghanistan ( (listen)), officially the Islamic Emirate of Afghanistan, is a landlocked country located at the crossroads of Central and South Asia. Referred to as the 'Heart of Asia', it is bordered by Pakistan to the east and south, Iran to the west, Turkmenistan to the northwest, Uzbekistan to the north, Tajikistan to the northeast, and China to the northeast and east. Occupying 652,864 square kilometers (252,072 sq mi) of land, the country is predominately mountainous with plains in the north and the southwest, which are separated by the Hindu Kush mountain range. As of 2021, its population is 40.2 million, composed mostly of ethnic Pashtuns, Tajiks, Hazaras, and Uzbeks. Kabul is the country's largest city and serves as its capital.

Human habitation in Afghanistan dates back to the Middle Paleolithic era, and the country's strategic location along the historic Silk Road connected it to the cultures of other parts of Asia as well as Europe, leaving behind a mosaic of ethnolinguistic and religious groups that has influenced the modern Afghan nation. Known as the 'Graveyard of Empires', the land has historically been home to various peoples and has witnessed numerous military campaigns, including those by Alexander the Great, the Maurya Empire, Arab Muslims, the Mongols, the British, the Soviet Union, and most recently by an American-led coalition. Afghanistan also served as the source from which the Greco-Bactrians and the Mughals, among others, rose to form major empires. The various conquests and periods in both the Iranian and Indian cultural spheres made the area a center for Zoroastrianism, Buddhism, Hinduism, and later Islam throughout history.The modern state of Afghanistan began with the Durrani dynasty in the 18th century, with the Durrani Afghan Empire at its peak having spanned from eastern Iran to northern India. Following its decline and the death of Timur Shah, it was divided into the smaller independent kingdoms of Herat, Kandahar and Kabul, before being reunited in the 19th century after wars of unification led by Dost Mohammad Khan. During this time, Afghanistan became a buffer state in the Great Game between the British Empire (in British-ruled India) and the Russian Empire; from India, the British attempted to subjugate Afghanistan but were repelled in the First Anglo-Afghan War; however, the Second Anglo-Afghan War saw a British victory and the successful establishment of British political influence over Afghanistan. Following the Third Anglo-Afghan War in 1919, Afghanistan became free of foreign dominance, and eventually emerged as the independent Kingdom of Afghanistan in June 1926 under Amanullah Khan. This monarchy lasted almost 50 years, until Zahir Shah was overthrown in 1973, following which the Republic of Afghanistan was established. Since the late 1970s, Afghanistan's history has been dominated by extensive warfare, including coups, revolutions, invasions, insurgencies, and civil wars. The country is currently under the control of the Taliban, an Islamist political movement that returned to power in 2021 after a 20-year-long war with the United States and its allies.The country has high levels of terrorism, poverty, and child malnutrition. Afghanistan's economy is the world's 96th-largest, with a gross domestic product (GDP) of $72.9 billion by purchasing power parity; the country fares much worse in terms of per-capita GDP (PPP), ranking 169th out of 186 countries as of 2018.
