An Armada victory would still leave Spain fighting for control of England

What if the Spanish Armada had won in 1588?

Victory at sea would open a prolonged and politically dangerous invasion, with supply problems, foreign intervention, and broad resistance making a stable Spanish settlement unlikely.

A successful Armada would leave an invading army supporting a long maritime supply line while campaigning through difficult English and Welsh terrain. Executing Elizabeth could create a martyr and unite resistance around James VI, while leaving her free would preserve an organiser. Scottish intervention and possible Danish or Swedish involvement could widen the conflict. Irish reactions would remain divided by family loyalties. English Catholic identity would not necessarily translate into support for Spain, with the Arundells offered as an example of resistance to foreign rule.
