What group established great zimbabwe

The Kingdom of Zimbabwe, of which Great Zimbabwe was its capital, was formed by the Shona, a Bantu-speaking people that had first migrated to southern Africa from the 2nd century CE.

Shona

Explanation:

The Great Zimbabwe area was settled by the fourth century AD. Between the fourth and the seventh centuries, communities of the Gokomere or Ziwa cultures farmed the valley, and mined and worked iron, but built no stone structures. These are the earliest Iron Age settlements in the area identified from archaeological diggings. Great Zimbabwe is an ancient city in the south-eastern hills of Zimbabwe near Lake Mutirikwe and the town of Masvingo. It is thought to have been the capital of a great kingdom, although which kingdom is not certain, during the country's Late Iron Age. Construction on the city began in the 11th century and continued until it was abandoned in the 15th century. The edifices are believed to have been erected by the ancestral Shona. The stone city spans an area of 7.22 square kilometers which, at its peak, could have housed up to 18,000 people. It is recognized as a World Heritage site by UNESCO.
