Iran (ایران), also known as Persia, officially the Islamic Republic of Iran (جمهوری اسلامی ایران), is a sovereign state in Western Asia. With over 81 million inhabitants, Iran is the world's 18th-most-populous country. Comprising a land area of, it is the second-largest country in the Middle East and the 17th-largest in the world. Iran is bordered to the northwest by Armenia and the Republic of Azerbaijan, to the north by the Caspian Sea, to the northeast by Turkmenistan, to the east by Afghanistan and Pakistan, to the south by the Persian Gulf and the Gulf of Oman, and to the west by Turkey and Iraq. The country's central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, give it geostrategic importance. Tehran is the country's capital and largest city, as well as its leading economic and cultural center. Iran is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BCE. It was first unified by the Iranian Medes in the seventh century BCE, reaching its greatest territorial size in the sixth century BCE, when Cyrus the Great founded the Achaemenid Empire, which stretched from Eastern Europe to the Indus Valley, becoming one of the largest empires in history. The Iranian realm fell to Alexander the Great in the fourth century BCE and was divided into several Hellenistic states. An Iranian rebellion culminated in the establishment of the Parthian Empire, which was succeeded in the third century CE by the Sasanian Empire, a leading world power for the next four centuries. Arab Muslims conquered the empire in the seventh century CE, displacing the indigenous faiths of Zoroastrianism and Manichaeism with Islam. Iran made major contributions to the Islamic Golden Age that followed, producing many influential figures in art and science. After two centuries, a period of various native Muslim dynasties began, which were later conquered by the Turks and the Mongols. The rise of the Safavids in the 15th century led to the reestablishment of a unified Iranian state and national identity, with the country's conversion to Shia Islam marking a turning point in Iranian and Muslim history. Under Nader Shah, Iran was one of the most powerful states in the 18th century, though by the 19th century, a series of conflicts with the Russian Empire led to significant territorial losses. Popular unrest led to the establishment of a constitutional monarchy and the country's first legislature. A 1953 coup instigated by the United Kingdom and the United States resulted in greater autocracy and growing anti-Western resentment. Subsequent unrest against foreign influence and political repression led to the 1979 Revolution and the establishment of an Islamic republic, a political system that includes elements of a parliamentary democracy vetted and supervised by a theocracy governed by an autocratic "Supreme Leader". During the 1980s, the country was engaged in a war with Iraq, which lasted for almost nine years and resulted in a high number of casualties and economic losses for both sides. According to international reports, Iran's human rights record is exceptionally poor. The regime in Iran is undemocratic, and has frequently persecuted and arrested critics of the government and its Supreme Leader. Women's rights in Iran are described as seriously inadequate, and children's rights have been severely violated, with more child offenders being executed in Iran than in any other country in the world. Since the 2000s, Iran's controversial nuclear program has raised concerns, which is part of the basis of the international sanctions against the country. The Joint Comprehensive Plan of Action, an agreement reached between Iran and the P5+1, was created on 14 July 2015, aimed to loosen the nuclear sanctions in exchange for Iran's restriction in producing enriched uranium. Iran is a founding member of the UN, ECO, NAM, OIC, and OPEC. It is a major regional and middle power, and its large reserves of fossil fuels – which include the world's largest natural gas supply and the fourth-largest proven oil reserves – exert considerable influence in international energy security and the world economy. The country's rich cultural legacy is reflected in part by its 22 UNESCO World Heritage Sites, the third-largest number in Asia and eleventh-largest in the world. Iran is a multicultural country comprising numerous ethnic and linguistic groups, the largest being Persians (61%), Azeris (16%), Kurds (10%), and Lurs (6%).

Keenleyside Dam

Hugh Keenleyside Dam (originally known as the High Arrow Dam is a flood control dam spanning the Columbia River, 12 km (6.5 miles) upstream of the city of Castlegar, British Columbia, Canada. The dam is at the outflow of what was the upper and lower Arrow Lakes, today the two lakes are joined forming one long reservoir extending north to Revelstoke Dam, and contains 8.76 km3 (7.1 MAF) of reservoir volume. The dam is operated by BC Hydro. The long earth fill and concrete dam was built as part of fulfilling Canada's role in the Columbia River Treaty, along with the Duncan Dam, both were built to prevent flooding and control the flow of water in the Columbia River for downstream hydroelectric dams. It was commissioned on October 10, 1968, six months ahead of schedule. Immediately downstream of the dam a 185 megawatt (MW) hydroelectric powerhouse, the Arrow Lakes Generating Station, was begun in 1999 and completed in 2002. The station is owned by the Columbia Power Corporation. Lower Arrow Lake was raised 12 metres (40 feet) above the natural levels, resulting in several towns being dismantled and relocated before their sites were flooded, including Burton. The dam was named after Hugh Llewellyn Keenleyside, the Canadian ambassador to Mexico, 1944-1947. Hugh Keenleyside served as the chairman of the British Columbia Power Commission and co-chairman at the British Columbia Hydro and Power Authority from 1962 to 1969. The Arrow Lakes reservoir is described by BC Hydro as a "great waterway for boating", despite the effect that the difference between high and low water has on docks and ramps. The dam is equipped with a navigation lock, which is available at no charge to boaters. However, commercial traffic and floating logs have priority over leisure crafts.
