If England discovered the Azores and Cape Verde in 1412

How would English possession of the Azores and Cape Verde from 1412 affect the race for the New World, and what might the islands be called?

They could become the Sovereign Islands: early Atlantic bases that accelerate English exploration while creating an immediate protection problem.

Henry IV is identified as the reigning king in the 1412 scenario, after an initial uncertainty about the date. Naming the islands after the monarch or Joan of Navarre gives way to the proposed Sovereign Islands, drawn from Henry's personal motto. Possession would give England Atlantic bases for expeditions at an earlier stage. Those bases would also require defence against Portuguese and Spanish competitors. Their distance from the mainland makes them possible locations for training loyal forces or removing political rivals from immediate English affairs. These are proposed consequences of the counterfactual discovery, with no fixed route to later empire.
