In Achaemenid Egypt a rebellion began under the command of Inaros, a Libyan king living on the border of Egypt. This rebellion quickly swept the country, which was soon largely in the hands of Inaros. He requested assistance from Athens which was granted. The alliance defeated the Persianw at the Battle of Papremis (460 BC). The remnants of defeated Persian force retreated to Memphis. So the alliance began to the Siege of Memphis (459–455 BCE) which was lifted by a Persian relief force which defeated the alliance. Then ended the Egyptian expedition of Athens. But What if the alliance captured Memphis and defeated the Persian relief force thereby securing Egypt. Using Egyptian assistance Athens defeats Sparta in the First Peloponnesian War and dissolves the Peloponnesian League while installing a puppet regime in Sparta. Later Athens along with Egypt convinces Satraps in Anatolia and Levant to rebel. This coalition defeats Persia and dissolves it's Empire.
