u mean king of sparta, cleomenes III ??
Cleomenes III, King of Sparta died in 219 BC.
In 222 BC, Cleomenes was defeated in the Battle of Sellasia by
the Achaeans, who received military aid from Antigonus III Doson of
Macedon. Cleomenes left Sparta and sought refuge at Alexandria with
Ptolemy Euergetes of Egypt, hoping for assistance to regain his
throne.
However, when Ptolemy died, his son and successor, Ptolemy
Philopator neglected Cleomenes and eventually put him under house
arrest. Together with his friends, he escaped his house arrest in
219 BC and tried to incite a revolt. When he received no support
from the population of Alexandria, he avoided capture by committing
suicide. Thus died the man who nearly conquered all of the
Peloponnese and is described by William Smith as "the last truly
great man of Sparta, and, excepting perhaps Philopoemen, of all
Greece."
