A Brief Overview
Isaiah in conventional dating prophesied for about 50 years from ca. 740 to 690 BCE.
According to the Talmud, Isaiah was the brother of King Amaziah of Judah (father of King Uzziah) and the father-in-law of Hezekiah. King Manasseh of Judah was his grandson and also his executioner (Talmud, Yevamot 49b).
Isaiah lived for 120 years (Agadat Breishit 14, Chasidah).
Isaiah was therefore himself of royal blood of the House of David.
The teachings of Isaiah influenced the early Zoroastrian religion of Iran some of whose texts resembles translations of Isaiah.

The name Isaiah in Hebrew is "Yeshiyahu" meaning the "The LORD Saves".
Isaiah speaks of Judah and Israel (the Ten Tribes). The emphasis is more on Judah though much concerning the Ten Tribes and their future history is also given.
Other nations are discussed as well, such as the Philistines, Damascus, Elam, Media, Edom, etc.
A Midrash (Pesikta Rabah 33;25).says that Isaiah prophesied concerning all nations of the earth.
The warnings of Isaiah were not heeded but Perhaps they were not meant to be?
Prophecies often have several applications.
Isaiah is important because of his Prophecies concerning the Present-Day End Times rather than their applicability to his own era.
