I don't know why everyone is saying almost no one would be happy, plenty would be.

Some of the non-southern early leaders of America would probably be happy.

Nationalist leaders may as well, if someone like the leader of Serbia defeated by the Ottomans came back and saw that his nation regained its independence.

I guess the early Chinese leaders (of like the Shang or Zhou dynasty) may be glad that their nation was so much larger (but displeased that they were not still in charge).

Muhammed would probably be pleased that Islam grew so much after his death.

The early English leaders would probably be happy their nation now dominates over Wales, Scotland, and parts of Ireland and their language is widely spoken.

The past kings of Sardinia would be pleased that their kingdom would unite Italy for a while. Same for the Prussian kings with Germany and the Muscovian kings with Russia.

The pre-Ghenghis Mongol leaders would probably be more shocked than anything to what their people achieved. Same for the leaders of early Rome.
