Prince Rupert of the Rhine in the context of "Cavaliers"

Debris (UK: /ˈdɛbri, ˈdeɪbri/, US: /dəˈbriː/) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, or, as in geology, large rock fragments left by a melting glacier, etc. Depending on context, debris can refer to a number of different things. The first apparent use of the French word in English is in a 1701 description of the army of Prince Rupert upon its retreat from a battle with the army of Oliver Cromwell, in England.

Rupert's Land (French: Terre de Rupert), or Prince Rupert's Land (French: Terre du Prince Rupert), was a territory in British America (British North America after 1783) based on the Hudson Bay drainage basin. The right to "sole trade and commerce" over Rupert's Land was granted to the Hudson's Bay Company (HBC), based at York Factory, effectively giving that company a commercial monopoly over the area. The territory operated for 200 years from 1670 to 1870. Its namesake was Prince Rupert of the Rhine, who was a nephew of King Charles I and the first governor of the HBC. In December 1821, the HBC monopoly was extended from Rupert's Land to the Pacific coast.

The areas formerly belonging to Rupert's Land lie mostly within what is today Canada, and included the whole of Manitoba, most of Saskatchewan, southern Alberta, southern Nunavut, and northern parts of Ontario and Quebec. Additionally, it also extended into areas that would eventually become parts of Minnesota, North Dakota, and Montana. The southern border west of Lake of the Woods to the Rocky Mountains was the drainage divide between the Mississippi and Red/Saskatchewan watersheds until the Anglo-American Convention of 1818 substituted the 49th parallel.

The Relief of Newark (21 March 1644) was a Royalist victory during the First English Civil War. It was a personal victory for Prince Rupert and it resulted in the Royalists holding Newark-on-Trent until almost the end of the war.

The Royal African Company (RAC) was an English trading company established in 1660 by the House of Stuart and City of London merchants to trade along the West African coast. It was overseen by the Duke of York, the brother of Charles II of England; the RAC was founded after Charles II ascended to the English throne in the 1660 Stuart Restoration, and he granted it a monopoly on all English trade with Africa. While the company's original purpose was to trade for gold in the Gambia River, as Prince Rupert of the Rhine had identified gold deposits in the region during the Interregnum, the RAC quickly began trading in slaves, who became its largest commodity.

Historians have estimated that the RAC shipped more African slaves to the Americas during the Atlantic slave trade than any other company. The RAC also dealt in other commodities such as ivory, which were primarily sourced from the Gold Coast region. After William III of England rescinded the company's monopoly in 1697 under pressure from the Parliament of England, the RAC became insolvent by 1708, though it survived in a state of much reduced activity until 1752, when its assets were transferred to the newly founded African Company of Merchants, which lasted until 1821.

The Battles of Schooneveld were two naval battles of the Franco-Dutch War, fought off the coast of the Netherlands on 7 June and 14 June 1673 (New Style; 28 May and 4 June in the Julian calendar then in use in England) between an allied Anglo-French fleet commanded by Prince Rupert of the Rhine on his flagship the Royal Charles, and the fleet of the United Provinces, commanded by Michiel de Ruyter.

The Dutch victories in the two battles, and at the Battle of the Texel that followed in August, saved their country from an Anglo-French invasion.
