Aboriginal is a term used to describe the people and animals that lived in a place from the earliest known times or before Europeans arrived. Examples are the Maori in New Zealand, the Aborigines in Australia and the Indians in South America.

Maori

The Maori were the first people to go to New Zealand about 1,000 years ago. They came from the islands of Polynesia in the Pacific. They brought dogs, rats and plants with them and settled mainly on the Northern Island. In 1769, Captain James Cook took possession of the Island, and from that time on British people started to settle. The Maori signed an agreement with these settlers, but in later years there were arguments and battles between them over land rights.

Aborigine

Native people of Australia came from somewhere in Asia more than 40,000 years ago. They lived by hunting and gathering. Their contact with British settlers began in 1788. By the 1940s almost all of them were mixed into Australian society as low-paid workers. Their rights were limited. In 1976 and 1993 the Australian government passed laws that returned some land to the Aborigines and recognized their property rights.

Indians

Long before the Europeans came to America in the 16th and 17th century, the American Indians, or Native Americans, lived there. It is believed that they came from Asia. Christopher Columbus mistook the land for India and so called the people there Indians. The white settlers and American Indians lived in peace at the beginning, but conflicts finally arose and led to the Indian Wars (1866 —1890). After the war the Indians were driven to the west of the country. Not until 1924 did they gain the right to vote.
