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. Perhaps some Slavs migrated with the movement of the Vandals to Iberia and north Africa. <SEP> around the 6th century, slavs appeared on byzantine borders in great numbers. the byzantine records note that grass would not regrow in places where the slavs had marched through, so great were their numbers. after a military movement even the peloponnese and asia minor were reported to have slavic settlements. this southern movement has traditionally been seen as an invasive expansion. by the end of the 6th century, slavs had settled the eastern alps regions. <SEP> Brazil is the second largest with 5 million people claiming German ancestry. People of German origin are found in various places around the globe. 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. Other significant centres are Canada, Argentina, South Africa and France each accounting for at least 1 million. 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. <SEP> the hosts for both world cups were announced by the fifa executive committee on 2 december 2010. russia was selected to host the 2018 fifa world cup, making it the first time that the world cup will be hosted in eastern europe and making it the biggest country geographically to host the world cup. qatar was selected to host the 2022 fifa world cup, making it the first time a world cup will be held in the arab world and the second time in asia since the 2002 tournament in south korea and japan. also, the decision made it the smallest country geographically to host the world cup.
