Eurydice's chance to increase her husband's power came when the first war of the [[Diadochi]] sealed the fate of Perdiccas, making a new settlement necessary. An agreement was made at [[Treaty of Triparadisus|Triparadisus]] in [[Syria]] in 321 BC. Eurydice moved deftly enough to achieve the removal of the first two designated regents, [[Peithon]] and [[Arrhidaeus]] (a namesake of her husband), but was powerless to block the aspirations of [[Antipater]], whose position proved too powerful, and the latter was made the new regent; Philip Arrhidaeus and Eurydice were forced to follow Antipater back to Macedonia.

The regent died of natural causes the following year, nominating as his successor not his son [[Cassander]], but his friend and lieutenant, [[Polyperchon]]. Cassander's refusal to accept his father's decision sparked the [[Second War of the Diadochi]], in which Eurydice saw once again a chance to free Philip from the control of the regent.

An opportunity presented itself in 317 BC when Cassander expelled Polyperchon from Macedonia. Eurydice immediately allied herself with Cassander and persuaded her husband to nominate him as the new regent. Cassander reciprocated by leaving her in full control of the country when he left to campaign in [[Hellenistic Greece|Greece]].
