Nomads is the right answer.
Anyone who moves from one place to another rather residing in one place is called the nomads. There can be many reasons for the migration of the nomads such as herders change places because of the weather( that is not suitable for their animals). whereas, other nomads including that of the traders and merchants, travels move for exchanging of their goods.
Japan needed more land to feed its people, it turned to war for this. When they started attacking small nations no one was too worried. Then they went for bigger areas and the United States retaliated. It is said the U.S.A did nothing to stop Japan at the beginning, but they did. The United States embargoed Japan, this made even more complications in the Japanese empire. Japan later went on to attack Pearl Harbor and the Philippines as a result. Keep in mind, the only reason America embargoed japan was due to their aggressive expansion.
I hope I have been of assistance. Have a great day! :)
This is seriously 100% false we may change but Jesus does NOT
Jews were encouraged to leave the country, they forced Jews out of schools and professions like medicine and teaching, they banned Jew/Non-Jew relationships, segregation, forced them to wear the Star of David. The Nazis started off small, but eventually took away huge rights for them.
