There were several generals and kings in Spartan history ; you need to be more specific.
There was General Lysander, who conquered Greece and brought it under Spartan control around 400 BC.
If you're speaking of the leader of the battle of Thermopylae against the Persian empire ( the story behind the movie "300" ), that would be King Leonidus the 1st.
If you're speaking of the Trojan wars, started when Helen of Troy left her husband, the king of Sparta, that would be King Menalaus.

The real Spartan shield, known as the hoplon, was a crucial part of ancient Spartan warfare. It was large and round, providing protection for the soldier's body and forming a shield wall when soldiers stood shoulder to shoulder. This shield formation, called the phalanx, was a key tactic in ancient battles, allowing Spartan warriors to advance as a unified force and overwhelm their enemies. The hoplon symbolized the discipline and unity of the Spartan army, contributing to their reputation as formidable warriors in ancient Greece.
Ancient Greece did not necessarily exist as one country. There were many cities within Greece that governed themselves based on different governments. The Athenians did have a democracy, but the Spartan's government was militaristic. There were also monarchies, oligarchies and several other types of government.
