Annexing Scotland
Five years had gone by since Lukas had first begun taking action as the King of England, and though he was still yet to marry, he now lived full time in England where he had begun developing the Kingdom from a primitive feudal state, to an early modern one. Not only that, he had even begun overhauling the political structure in a way that was largely based on the designs of the German Reich which his father had established.
However, when compared to his brothers, who had already gotten a head start on building their Empires, Lukas was quite far behind, he had not even managed to unite the entirety of the British isles, with the isle of man, and Scotland both being independent of his Kingdom.
