Oldenburg attained its independence from Denmark in 1773 and in 1777 was elevated to the status of duchy. Thus, when the United States announced its independence from Great Britain in 1776, Oldenburg was a sovereign, independent state. Annexed by France in 1810, the Duchy of Oldenburg was restored and elevated to the status of Grand Duchy following the 1815 Congress of Vienna. The United States and the Grand Duchy of Oldenburg mutually recognized each other in 1829.

During the 1866 Austro-Prussian War, Oldenburg sided with Prussia. In 1867 Oldenburg was incorporated into the North German Confederation, after which point foreign policy for the new confederation was conducted out of Berlin. Oldenburg, like the other North German Confederation members, joined the German Empire in 1871. From this point forward, foreign policy of the German Empire was made in Berlin, with the German Kaiser (who was also the King of Prussia) accrediting ambassadors of foreign nations. Relations with Imperial Germany were severed when the U.S. declared war in 1917.

Oman (/oʊˈmɑːn/ ⓘ oh-MAHN; Arabic: عُمَان, [ʕʊˈmaːn]), officially the Sultanate of Oman (Arabic: سلْطنةُ عُمان Salṭanat(u) ʻUmān), is a country located in West Asia. It is situated on the southeastern coast of the Arabian Peninsula, and spans the mouth of the Persian Gulf. It shares land borders with Saudi Arabia, United Arab Emirates, and Yemen, while sharing maritime borders with Iran and Pakistan. 

The capital and largest city is Muscat. Oman has a population of 5,492,196 and is ranked the 120th most populous country. The coast is formed by the Arabian Sea on the southeast, and the Gulf of Oman on the northeast. The Madha and Musandam exclaves are surrounded by United Arab Emirates on their land borders, with the Strait of Hormuz (which it shares with Iran) and the Gulf of Oman forming Musandam’s coastal boundaries.

From the 17th century, the Omani Sultanate was an empire, vying with the Portuguese and British Empires for influence in the Persian Gulf and Indian Ocean. At its peak in the 19th century, Omani influence and control extended across the Strait of Hormuz to Iran and Pakistan, and as far south as Zanzibar. 

In the 20th century, the sultanate came under the influence of the United Kingdom. For over 300 years, the relations built between the two empires were based on mutual benefit. The UK recognized Oman’s geographical importance as a trading hub that secured their trading lanes in the Persian Gulf and Indian Ocean and protected their empire in the Indian sub-continent. 

Oman is an absolute monarchy led by a Sultan, with power passed down through the male line. Qaboos bin Said was the Sultan from 1970 until his death on 10 January 2020. Qaboos, who died childless, had named his cousin, Haitham bin Tariq, as his successor in a letter, and the family confirmed him as the Sultan of Oman.

Formerly a maritime empire, Oman is the oldest continuously independent state in the Arab world. It is a member of the United Nations, the Arab League, the Gulf Cooperation Council, the Non-Aligned Movement and the Organisation of Islamic Cooperation. It has oil reserves ranked 22nd globally.

In 2010, the United Nations Development Programme ranked Oman as the most improved nation in the world in terms of development during the preceding 40 years. A portion of its economy involves tourism and trading fish, dates and other agricultural produce. Oman is categorized as a high-income economy and, as of 2022, ranks as the 64th most peaceful country in the world according to the Global Peace Index.

Orange Free State*

• Continent: Southern Africa
• Capital: Bloemfontein
• National language: Dutch
• Religion: Dutch Reformed
• Area: 181,299 km2
• Population: 100,000
• Currency: Orange Free State pound
• GDP (nominal): N/A

The Orange Free State (Dutch: Oranje Vrijstaat; Afrikaans: Oranje-Vrystaat;) was an independent Boer sovereign republic under British suzerainty in Southern Africa during the second half of the 19th century, which ceased to exist after it was defeated and surrendered to the British Empire at the end of the Second Boer War in 1902. It is one of the three historical precursors to the present-day Free State province.

Extending between the Orange and Vaal rivers, its borders were determined by the United Kingdom of Great Britain and Ireland in 1848 when the region was proclaimed as the Orange River Sovereignty, with a British Resident based in Bloemfontein. Bloemfontein and the southern parts of the Sovereignty had previously been settled by Griqua and by Trekboere from the Cape Colony.

The Voortrekker Republic of Natalia, founded in 1837, administered the northern part of the territory through a landdrost based at Winburg. This northern area was later in federation with the Republic of Potchefstroom which eventually formed part of the South African Republic (Transvaal).

Following the granting of sovereignty to the Transvaal Republic, the British sought to drop their defensive and administrative responsibilities between the Orange and Vaal rivers, while local European residents wanted the British to remain. This led to the British recognising the independence of the Orange River Sovereignty and the country officially became independent as the Orange Free State on 23 February 1854, with the signing of the Orange River Convention. The new republic incorporated the Orange River Sovereignty and continued the traditions of the Winburg-Potchefstroom Republic.

The Orange Free State was annexed as the Orange River Colony in 1900. It ceased to exist as an independent Boer republic on 31 May 1902 with the signing of the Treaty of Vereeniging at the conclusion of the Second Boer War. Following a period of direct rule by the British, it attained self-government in 1907 and joined the Union of South Africa in 1910 as the Orange Free State Province, along with the Cape Province, Natal, and the Transvaal. In 1961, the Union of South Africa became the Republic of South Africa.

The Republic’s name derives partly from the Orange River, which was named by the Dutch explorer Robert Jacob Gordon in honour of the Dutch ruling family, the House of Orange, whose name in turn derived from its partial origins in the Principality of Orange in French Burgundy. The official language in the Orange Free State was Dutch.
