Question: Richard Cumberland wrote plays that involved a process called what?

full_context: Document 1: Monthly Review (London): The Monthly Review. (1749–1845) was an English periodical founded by Ralph Griffiths, a Nonconformist bookseller. The first periodical in England to offer reviews, it featured the novelist and poet Oliver Goldsmith as an early contributor. Griffiths himself, and likely his wife Isabella Griffiths, contributed review articles to the periodical. Later contributors included Dr. Charles Burney, John Cleland, Theophilus Cibber, James Grainger, Anna Letitia Barbauld, Elizabeth Moody, and Tobias Smollett—who would go on to establish the "Monthly"'s competitor in 1756, "The Critical Review". William Kenrick, the "superlative scoundrel", was editor from 1759 to 1766.
Document 2: Former colonies and territories in Canada: A number of states and polities formerly claimed colonies and territories in Canada prior to the evolution of the current provinces and territories under the federal system. North America prior to colonization was occupied by a variety of Aboriginal polities of different complextions, from small independent band societies typical of the sparsely populated North, to loose confederacies made up of numerous hunting bands from a variety of ethnic groups (Plains region), to more structured confederacies of sedentary farming villages (Great Lakes region), to stratified hereditary structures centred on a fishing economy (Plateau and Pacific Coast regions). The colonization of Canada by Europeans began in the 10th century, when Norsemen explored and, ultimately unsuccessfully, attempted to settle areas of the northeastern fringes of North America. Early permanent European settlements in what is now Canada included the late 16th and 17th century French colonies of Acadia and Canada (New France), the English colonies of Newfoundland (island) and Rupert's Land, the Scottish colonies of Nova Scotia and Port Royal.
Document 3: Postcolonial literature: Postcolonial literature is the literature of countries that were colonised, mainly by European countries. It exists on all continents except Antarctica. Postcolonial literature often addresses the problems and consequences of the decolonization of a country, especially questions relating to the political and cultural independence of formerly subjugated people, and themes such as racialism and colonialism. A range of literary theory has evolved around the subject.
Document 4: David Garrick: David Garrick (19 February 1717 – 20 January 1779) was an English actor, playwright, theatre manager and producer who influenced nearly all aspects of theatrical practice throughout the 18th century, and was a pupil and friend of Dr Samuel Johnson. He appeared in a number of amateur theatricals, and with his appearance in the title role of Shakespeare's "Richard III", audiences and managers began to take notice.
Document 5: The Drama of King Shotaway: The Drama of King Shotaway, founded on Facts taken from the Insurrection of the Caravs on the Island of St. Vincent, written from Experience by Mr. Brown (1823) was a play believed to be by William Henry Brown. This was the first known play by a black playwright in the United States. No known copies of the play exist.
Document 6: List of countries with overseas military bases: This is a list of overseas military bases by country. The establishment of military bases abroad enable a country to project power, e.g. to conduct expeditionary warfare, and thereby influence events abroad. Depending on their size and infrastructure, they can be used as staging areas or for logistical, communications and/or intelligence support. Many conflicts throughout modern history have resulted in overseas military bases being established in large numbers by world powers and the existence of bases abroad has served countries having them in achieving political and military goals. The British Empire and other colonial powers established overseas military bases in many of their colonies during the First and Second World Wars, where useful, and actively sought rights to facilities where needed for strategic reasons. At one time, establishing coaling stations for naval ships was important. During the Cold War, the United States and the Soviet Union established military bases where they could within their respective spheres of influence, and actively sought influence where needed. More recently, the War on Terror has resulted in overseas military bases being established in the Middle East.
Document 7: Indigenous peoples: Indigenous peoples, also known as first peoples, aboriginal peoples, native peoples, or autochthonous peoples, are ethnic groups who are descended from and identify with the original inhabitants of a given region, in contrast to groups that have settled, occupied or colonized the area more recently. Groups are usually described as indigenous when they maintain traditions or other aspects of an early culture that is associated with a given region. Not all indigenous peoples share this characteristic, sometimes having adopted substantial elements of a colonising culture, such as dress, religion or language. Indigenous peoples may be settled in a given locale/region or exhibit a nomadic lifestyle across a large territory, but they are generally historically associated with a specific territory on which they depend. Indigenous societies are found in every inhabited climate zone and continent of the world.
Document 8: Richard Hakluyt: Richard Hakluyt ( , , or ; 1553 – 23 November 1616) was an English writer. He is known for promoting the English colonization of North America through his works, notably "Divers Voyages Touching the Discoverie of America" (1582) and "The Principal Navigations, Voiages, Traffiques and Discoueries of the English Nation" (1589–1600).
Document 9: Richard Stirling: Richard Stirling is a British writer and actor, who has appeared on film, television and the West End and American stage. He has written arts features for many newspapers and magazines, and drew attention for his 2009 play Seven Other Children, penned as a response to Caryl Churchill's controversial play Seven Jewish Children.
Document 10: Colonialism: Colonialism is the establishment of a colony in one territory by a political power from another territory, and the subsequent maintenance, expansion, and exploitation of that colony. Colonialism involves unequal relationships between the colonial power and the colony and often between the colonists and the indigenous peoples.
Document 11: Expansionist nationalism: Expansionist nationalism is an aggressive and radical form of nationalism that incorporates autonomous, patriotic sentiments with a belief in expansionism. The term was coined during the late nineteenth century as European powers indulged in the 'Scramble for Africa' in the name of national glory, but has been most associated with militarist governments during the 20th century including Fascist Italy, Nazi Germany, the Japanese empire, and the Balkans countries of Albania (Greater Albania), Croatia (Greater Croatia) and Serbia (Greater Serbia).
Document 12: Colonial history of the United States: The colonial history of the United States covers the history of European settlements from the start of colonization in the early 16th century until their incorporation into the "United States of America" in 1776. In the late 16th century, England, France, Spain, and the Netherlands launched major colonization programs in eastern North America. Small early attempts sometimes disappeared, such as the English Lost Colony of Roanoke. Everywhere, the death rate was very high among the first arrivals. Nevertheless, successful colonies were established within several decades.
Document 13: Richard Cumberland (dramatist): Richard Cumberland (19 February 1731/2 – 7 May 1811) was an English dramatist and civil servant. In 1771 his hit play "The West Indian" was first staged. During the American War of Independence he acted as a secret negotiator with Spain in an effort to secure a peace agreement between the two nations. He also edited a short-lived critical journal called "The London Review" (1809). His plays are often remembered for their sympathetic depiction of colonial characters and others generally considered to be margins of society.
Document 14: Exploitation colonialism: Exploitation colonialism is the national economic policy of conquering a country to exploit its natural resources and its native population. The practice of exploitation colonialism contrasts with settler colonialism, the policy of conquering a country to establish a branch of the metropole (Motherland), and for the exploitation of its natural resources and native population. A colonialist power pursues settler colonialism to relieve the pressures of over-population upon the economy and the national territory of the motherland, and to extend its territory and culture by reproducing its society in other parts of the world. A reason for which a country might practice exploitation colonialism is the immediate financial gain produced by the low-cost extraction of raw materials by means of a native people, usually administered by a colonial government.
Document 15: Jan Carew: Jan Rynveld Carew (24 September 1920 – 6 December 2012) was a Guyana-born novelist, playwright, poet and educator, who lived at various times in The Netherlands, Mexico, England, France, Spain, Ghana, Jamaica, Canada and the United States. His works, diverse in form and multifaceted, make Jan Carew an important intellectual of the Caribbean world. His poetry and his first two novels, "Black Midas" and "The Wild Coast" (both published in 1958 by Secker & Warburg in London), were significant landmarks of the West Indian literature then attempting to cope with its colonial past and assert its wish for autonomy. He worked with the late President Cheddi Jagan in the fight for Guianese independence. Carew also played an important part in the Black movement gaining strength in England and North America, publishing reviews and newspapers, producing programs and plays for the radio and the television. His scholarly research drove him to question traditional historiographies and the prevailing historical models of the conquest of America. The way he reframed Christopher Columbus as an historical character outside his mythical hagiography became a necessary path in his mind to build anew the Caribbean world on sounder foundations.
