Read this: In 1211, the Jewish community in the country was strengthened by the arrival of a group headed by over 300 rabbis from France and England, among them Rabbi Samson ben Abraham of Sens. Nachmanides, the 13th-century Spanish rabbi and recognised leader of Jewry greatly praised the land of Israel and viewed its settlement as a positive commandment incumbent on all Jews. He wrote "If the gentiles wish to make peace, we shall make peace and leave them on clear terms; but as for the land, we shall not leave it in their hands, nor in the hands of any nation, not in any generation."
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Who was the 13th-century Spanish rabbi and recognised leader of Jewry?
Nachmanides
