What were some important results of william’s conquest?

The Norman conquest of England, led by William the Conqueror (r. 1066-1087 CE) was achieved over a five-year period from 1066 CE to 1071 CE. Hard-fought battles, castle building, land redistribution, and scorched earth tactics ensured that the Normans were here to stay. The conquest saw the Norman elite replace that of the Anglo-Saxons and take over the country’s lands, the Church was restructured, a new architecture was introduced in the form of motte and bailey castles and Romanesque cathedrals, feudalism became much more widespread, and the English language absorbed thousands of new French words, amongst a host of many other lasting changes which all combine to make the Norman invasion a momentous watershed in English history.

explanation:

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
