posiden was said to be the ruler of the oceans and lakes.
Greeks mainly traveled by sea, and Poseidon is the god of the sea. So he had more influence upon the Greeks. He also had control of earthquakes and more earthly matters so they naturally made him a little more important.
Either the telekinesis or the Cyclopes made Poseidon's trident, at least it says so in the myths.
Depends on your definition of important. I do know that he is the God of the sea and that he made horses.
Because Odysseus blinded Poseidon's son Polyphemus, so then Polyphemus made a prayer to his father (Poseidon) so then Poseidon cursed Odysseus with a hard journey home with many [arils.
odysseus blinded him
the reason why Poseidon sunk the city of Atlantis is that the people were so sinful that made Poseidon very angry and sent a tsunami to sink it...
Poseidon's trident was made by the cyclopes
Rhea and Cronus made poseidon.
To try and become patron of Athens but athena also wanted to be patron so she the olive tree and Poseidon made the horse
