What is the theme of William Shakespeare's The Tempest?the the of the book

One of the main themes in "The Tempest" is the
consequences of the uses and abuses of power. Prospero has accumulated and lost a great
deal of power in his life. For this reason, and because his brother is also
power-hungry, Prospero and his daughter Miranda have been banished to an island.
Prospero's only remaining power is controlling the weather and the other inhabitants of
the island: his daughter, his faery servant Ariel, and the monstrous Caliban. As the
play progresses, Shakespeare depicts Prospero as increasingly weary of using his powers;
he wants now only to make certain that his daughter has a future. He contrives a
shipwreck and stages a meeting between Miranda and a suitable husband. After all turns
out the way he planned, he yields his power to the future and returns
home.
