What did magellan and de gama do? -?

Magellan was the first person to circumnavigate the world. Well, one of his boats was, he was killed in the Philippines by the natives because he attacked them with his men (There is a whole background story that I won't elaborate into). :) He set off from Spain in 1519 and his last boat, the Victoria, reached Spain in 1522. It was the only boat of three that returned. 
Vasco da Gama was the fist European to reach India by sea. He sailed all the way from Portugal to India going around Africa. 
Hope this helps! Please let me know if I'm wrong :) 

In 911, a group of vikings lead by rollo besieged paris and chartres. after a victory near chartres on 26 august, charles decided to negotiate with rollo. the talks were led by hervé, the archbishop of reims. this resulted in the treaty of saint-clair-sur-epte, which granted rollo and his soldiers all the land between the river epte and the sea. it also granted him brittany, "for his livelihood". at the time, brittany was an independent land which france had not been able to conquer. in exchange, rollo promised the king his loyalty and military assistance when needed. also rollo also agreed to be baptised and to marry gisela, the king's daughter. the territory given rollo is about the same as upper normandy.
