In the Bible, who dwelt in the land of Canaan before the Israelites invaded and drove them all out?

Canaan of course represents the promised land that is
"overflowing with milk and honey," and the land that God gives to his people, the
Israelites. However, as a significant part of the first few books of the Old Testament
go to show, this land is not just empty and waiting to be possessed by the Israelites. A
number of tribes have occupied it and are very strong and difficult to defeat, as the
Israelites believe. The names of these tribes can actually be found if we turn back to
the Book of Genesis, which details the Table of Nations and the origins of the first
tribes that filled the earth. In particular, consider Genesis
10:15-19:

Canaan was the father of Sidon his firstborn,
and of the Hittites, Hebusites, Amorites, Girgashites, Hivites, Arkites, Sinites,
Arvadites, Zemarites and Hamathites. Later the Canaanite clans scattered and the borded
or Canaan reached from Sidon towards Gerar as far as Gaza, and then towards Sodom,
Gomorrah, Admah and Zebolim, as far as
Lasha.

Thus we can see the
origins of the lands of Canaan and the names of the various tribes that populated it,
all descending from Canaan himself. The Israelites have to face many struggles and
trials and battles before finally occupying the land that they felt was given to them by
God.
