New Amsterdam (Dutch: Nieuw Amsterdam, pronounced [nimstrdm] or [niums-]) was a 17th-century Dutch settlement established at the southern tip of Manhattan Island that served as the seat of the colonial government in New Netherland. The initial trading factory gave rise to the settlement around Fort Amsterdam. The fort was situated on the strategic southern tip of the island of Manhattan and was meant to defend the fur trade operations of the Dutch West India Company in the North River (Hudson River). In 1624, it became a provincial extension of the Dutch Republic and was designated as the capital of the province in 1625.

By 1655, the population of New Netherland had grown to 2,000 people, with 1,500 living in New Amsterdam. By 1664, the population of New Netherland had risen to almost 9,000 people, 2,500 of whom lived in New Amsterdam, 1,000 lived near Fort Orange, and the remainder in other towns and villages.In 1664, the English took over New Amsterdam and renamed it New York after the Duke of York (later James II & VII). After the Second Anglo-Dutch War of 166567, England and the United Provinces of the Netherlands agreed to the status quo in the Treaty of Breda. The English kept the island of Manhattan, the Dutch giving up their claim to the town and the rest of the colony, while the English formally abandoned Surinam in South America, and the island of Run in the East Indies to the Dutch, confirming their control of the valuable Spice Islands. What was once New Amsterdam became New York City's downtown, today known as Lower Manhattan.

The United Provinces of the Netherlands, or United Provinces (officially the Republic of the Seven United Netherlands), commonly referred to in historiography as the Dutch Republic, was a federal republic which existed from 1588 (during the Dutch Revolt) to 1795 (the Batavian Revolution). It was a predecessor state of the Netherlands and the first fully independent Dutch nation state.

The republic was established after seven Dutch provinces in the Spanish Netherlands revolted against rule by Spain. The provinces formed a mutual alliance against Spain in 1579 (the Union of Utrecht) and declared their independence in 1581 (the Act of Abjuration). It comprised Groningen, Frisia, Overijssel, Guelders, Utrecht, Holland and Zeeland.

Although the state was small and contained only around 1.5 million inhabitants, it controlled a worldwide network of seafaring trade routes. Through its trading companies, the Dutch East India Company (VOC) and the Dutch West India Company (GWC), it established a Dutch colonial empire. The income from this trade allowed the Dutch Republic to compete militarily against much larger countries. It amassed a huge fleet of 2,000 ships, initially larger than the fleets of England and France combined. Major conflicts were fought in the Eighty Years' War against Spain (from the foundation of the Dutch Republic until 1648), the Dutch–Portuguese War (1602–1663), four Anglo-Dutch Wars (3 against the Kingdom of England and a fourth against the Kingdom of Great Britain: 1652–1654, 1665–1667, 1672–1674 and 1780–1784), the Franco-Dutch War (1672–1678), and War of the Grand Alliance (1688–1697) against the Kingdom of France.

The republic was more tolerant of different religions and ideas than its contemporary states were, allowing freedom of thought to its residents. Artists flourished under this regime, including painters such as Rembrandt, Johannes Vermeer and many others. So did scientists, such as Hugo Grotius, Christiaan Huygens and Antonie van Leeuwenhoek. Because Dutch trade, science, military, and art were among the most acclaimed in the world during much of the 17th century, this period became known in Dutch history as the Dutch Golden Age.

The republic was a confederation of provinces each with a high degree of independence from the federal assembly, known as the States General. In the Peace of Westphalia (1648) the republic gained approximately 20% more territory, located outside the member provinces, which was ruled directly by the States General as Generality Lands. Each province was led by an official known as the stadtholder (Dutch for 'steward'); this office was nominally open to anyone, but most provinces appointed a member of the House of Orange. The position gradually became hereditary, with the Prince of Orange simultaneously holding most or all of the stadtholderships, making them effectively the head of state. This created tension between political factions: the Orangists favoured a powerful stadtholder, while the Republicans favoured a strong States General. The Republicans forced two Stadtholderless Periods, 1650–1672 and 1702–1747, with the latter causing national instability and the end of Great Power status.

Economic decline led to a period of political instability known as the Patriottentijd (1780–87). This unrest was temporarily suppressed by a Prussian invasion in support of the stadtholder. The French Revolution and subsequent War of the First Coalition caused these tensions to reignite. Following military defeat by France, the stadtholder was expelled in the Batavian Revolution of 1795. This ended the Dutch Republic; it was succeeded by the Batavian Republic.
