Question: Who fathered the leader of the first expedition to reach the mentioned continent by sailing west across the ocean bordering eastern Russia?

explorers flying the flag of spain reached the new world beginning in 1492 with the discovery of america by christopher columbus. spanish expeditions colonized and explored vast areas in north and south america following the grants of the pope (contained in the 1493 papal bull inter caetera) and rights contained in the 1494 treaty of tordesillas and 1529 treaty of zaragoza. these formal acts gave spain the exclusive rights to colonize the entire western hemisphere (excluding eastern brazil), including all of the west coast of north america. the first european expedition to actually reach the west coast was led by the spaniard vasco núñez de balboa, who reached the pacific coast of panama in 1513. in an act of enduring historical importance, balboa claimed the pacific ocean for the spanish crown, as well as all adjoining land and islands. this act gave spain exclusive sovereignty and navigation rights over the entire west coast of north america. <SEP> asia is the largest continent on earth. it covers 8.8% of the earth's total surface area (or 30% of its land area), and has the largest coastline, at 62,800 kilometres (39,022 mi). asia is generally defined as comprising the eastern four - fifths of eurasia. it is located to the east of the suez canal and the ural mountains, and south of the caucasus mountains (or the kuma -- manych depression) and the caspian and black seas. it is bounded on the east by the pacific ocean, on the south by the indian ocean and on the north by the arctic ocean. asia is subdivided into 48 countries, three of them (russia, kazakhstan and turkey) having part of their land in europe. <SEP> He rose in the ranks of the military Order of Santiago.

Gender influences the pattern of child labor. Girls tend to be asked by their families to perform more domestic work in their parental home than boys are, and often at younger ages than boys. Employment as a paid domestic worker is the most common form of child labor for girls. Domestic service, however, is among the least regulated of all professions, and exposes workers to serious risks, such as violence, exploitation and abuse by the employers, because the workers are often isolated from the outside world. Child labor has a very negative effect on education. Girls either stop their education, or, when they continue it, they are often subjected to a double burden, or a triple burden of work outside the home, housework in the parental home, and schoolwork. This situation is common in places such as parts of Asia and Latin America. <SEP> The Portuguese Vasco da Gama, accompanied by Nicolau Coelho and Bartolomeu Dias, is the first European to reach India by an all - sea route from Europe.
