Certainty not magically, but it did disappear: https://en.wikipedia.org/wiki/Partition_of_the_Ottoman_Empir...

Formally through the Treaty of Sèvres and Treaty of Lausanne: https://en.wikipedia.org/wiki/Treaty_of_S%C3%A8vres

The thing coming closest to a successor state would be modern-day Turkey, I believe.

Creation of Mandatory Palestine (under British rule, but not considered a state) was a part of the partition.
