Question: How many people who started the great migration of the Slavs live in the colonial holding governed by Portugal from the continent the movie The Mission takes place in?

<P0-S0> People of German origin are found in various places around the globe. <P0-S1> United States is home to approximately 50 million German Americans or one third of the German diaspora, making it the largest centre of German-descended people outside Germany. <P0-S2> Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. <P0-S3> While the exact number of German-descended people is difficult to calculate, the available data makes it safe to claim the number is exceeding 100 million people. <P0-S4> Brazil is the second largest with 5 million people claiming German ancestry. <SEP> <P1-S0> at the time of the berlin conference, africa contained one-fifth of the world’s population living in one-quarter of the world’s land area. <P1-S1> however, from europe's perspective, they were dividing an unknown continent. <P1-S2> european countries established a few coastal colonies in africa by the mid-nineteenth century, which included cape colony (great britain), angola (portugal), and algeria (france), but until the late nineteenth century europe largely traded with free african states without feeling the need for territorial possession. <P1-S3> until the 1880s most of africa remained unchartered, with western maps from the period generally showing blank spaces for the continent’s interior. <SEP> <P2-S0> Written by Robert Bolt and directed by Roland Joffé, the film stars Robert De Niro, Jeremy Irons, Ray McAnally, Aidan Quinn, Cherie Lunghi, and Liam Neeson. <P2-S1> The Mission is a 1986 British period drama film about the experiences of a Jesuit missionary in 18th - century South America. <SEP> <P3-S0> the concept environmental determinism served as a moral justification for domination of certain territories and peoples. <P3-S1> it was believed that a certain person's behaviours were determined by the environment in which they lived and thus validated their domination. <P3-S2> for example, people living in tropical environments were seen as "less civilized" therefore justifying colonial control as a civilizing mission. <P3-S3> across the three waves of european colonialism (first in the americas, second in asia and lastly in africa), environmental determinism was used to categorically place indigenous people in a racial hierarchy. <P3-S4> this takes two forms, orientalism and tropicality. <SEP> <P4-S0> Although the royal family returned to Portugal in 1821, the interlude led to a growing desire for independence amongst Brazilians. <P4-S1> In 1822, the son of Dom João VI, then prince - regent Dom Pedro I, proclaimed the independence of Brazil on September 7, 1822, and was crowned Emperor of the new Empire of Brazil. <P4-S2> Unlike the Spanish colonies of South America, Brazil's independence was achieved without significant bloodshed. <SEP> <P5-S0> According to eastern homeland theory, prior to becoming known to the Roman world, Slavic-speaking tribes were part of the many multi-ethnic confederacies of Eurasia – such as the Sarmatian, Hun and Gothic empires. <P5-S1> Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa. <P5-S2> The Slavs emerged from obscurity when the westward movement of Germans in the 5th and 6th centuries CE (thought to be in conjunction with the movement of peoples from Siberia and Eastern Europe: Huns, and later Avars and Bulgars) started the great migration of the Slavs, who settled the lands abandoned by Germanic tribes fleeing the Huns and their allies: westward into the country between the Oder and the Elbe-Saale line; southward into Bohemia, Moravia, much of present-day Austria, the Pannonian plain and the Balkans; and northward along the upper Dnieper river.
