How did the Flight of the Earls strengthen English control over Ireland?

The "Flight of the Earls" in 1607, which involved the departure of the earls of Tyrone and Tyrconnell along with other Gaelic lords, significantly strengthened English control by signaling the end of traditional Gaelic power in Ulster.12

Their departure created a power vacuum that allowed the English crown to implement the Plantation of Ulster. This initiative replaced the former Gaelic leadership with a new, loyal landowning class composed of English and Scottish settlers. This settlement proved to be the most successful British effort of its kind, as it established a permanent, pro-English demographic presence in the region. By removing the primary figures of resistance, the English government was able to rapidly Anglicize the province and solidify its administrative and political authority over an area that had previously been the center of opposition to the crown.21
