King Solomon built the first Temple in 957 BCE with resources provided by his father King David. The second temple was allowed to be built by King Cyrus of Persia while the Jews were exiled in Babylon (536 BCE).

This edict was supported by King Darius (522-486 BCE) who followed King Cyrus. This is described in the book of Ezra.
It was king Cyrus of Persia that released the Jews from slavery in Babylon.
