Genoa, December 1339
Simone Boccanegra became the first doge of Genoa riding on the wave of a popular uprising led by the crews of the Genoese that had been hired out to the French king and had mutinied and returned to Genow after they had been left unpaid by their commander and Philip VI who had been actually paying had jailed their representatives who had tried to complain.
Sluys, June 1340
Earlier in the year the French navy, deprived of the majority of its Genoese mercenaries had lost 42 ships to an English raid. But this was nothing compared to the disaster that had now befallen it as it had been caught by the English at Sluys. Despite the French having numerical superiority, the English had had more marines and the French admirals were land commanders with no experience at sea. The French out of 213 ships would lose 190 and nearly 20,000 men. The English would lose 2 ships. The next month the French would extract some revenge on land when a French army of 3,000 men would crush an Anglo-Flemish army four times its sizes inflicting 8,000 casualties on it in the battle of Saint Omer.
Rio Salado, Spain, October 1340
Back in April the Marinid navy had scored a crushing victory against the Castilians with just 11 galleys out of 52 surviving. But the Castilians had immediately start a construction program completing 27 new galleys at Seville, had hired 15 more from Genoa and had received Portuguese reinforcements, Castilian diplomats had also gone to Barcelona and Syracuse seeking help but the Aragonese despite promising help had done little and Theodore was still consolidating his position thus had refused immediate help. With the situation at sea thus restored the Castilians and Portuguese had forced the Marinids and Granadans who were besieging Tarifa to battle decisively defeating them...
Constantinople, June 10th, 1341
For the past four years the Orthodox church was being torn over
Hesychasm a practice followed by the Athos monks and claimed by them to allow practitioners to see the light of mount Tabor. Barlaam of Calabria, Greek but steeped to the scholastic traditions of the west had attacked the claims of the monks as heretical. The monks had reacted by bringing forth
Gregory Palamas to defend their case and soon the controversy had turned bad enough to require calling a holy synod to solve the issue. Despite the initial absence of the emperor, the synod would proceed and condemn Barlaam who would be forced to repent by it. But the matter was not over as Palamas arguments did not stand all too well with the more logical minded members of the church [1] and soon more and better theologians than Barlaam would join the fray.
Syracuse, June 27th, 1341
"So you you decided in a hurry to leave Constantinople, after the synod."
"Yes your serenity. I saw no reason to stay. I had made my argument. It wasn't accepted as it should. and the supporters of Palamas are growing aggressive in the streets. I was hoping that your serenity would have some use for me here."
Theodore hid a smile, as he had a look at Adrienne at the throne on his side. The damn monk was of course trying to flatter him and laying it down thick hence the "your serenity", that was the way to address the basileus not a despot. But still he did have a use for him actually. "As a matter of fact I do Barlaam"
"Your serenity?"
"The realm has no institution of higher learning of its own. This is not something I want to see continuing. So I have decided to follow the example of my great-grandfather when he established a university in Naples. A university will be established in Syracuse and you will the man to see it established. Is this task sufficient for your talents? now I have to attend to the other news that came from Constantinople after you."
Barlaam of Calabria, never a man to lack confidence in himself smiled... then he noticed what Theodore had just said. "Other news, your serenity?"
"Why, it appears Andronikos died just a couple days after you left the City. I guess there will be a regency in the City. Ioannis is just 9."
Constantinople, July 1341
Megas Domestikos Ioannis Kantakouzenos presided over a second synod to deal with hesychasm, not even a month had passed from the previous synod for serious objections to be raised by Gregory Akindynos, a theologian and friend of patriarch John XIV against the teachings of his former teacher Palamas. But Palamas had the support of Kantakouzenos who presided over the synod, thus won once more with Akindynos verbally condemned. But the synod had other unexpected side effects. By presiding over it Kantakouzenos had taken for himself imperial prerogatives. Dowager empress Anne, Andronikos window, was suspocious of him even when Andronikos was alive. It did not need much to make her increasingly paranoid about the regent..."
Didymoteichon, October 26th, 1341
The relations between Kantakouzenos and Anne of Savoy had steadily deteriorated over the preceding months, till Anee influenced by megas doux
Alexios Apokaukos and the patriarch had taken advantage of Kantakouzenos moving with the army in Thrace to dismiss him from the regency and all his others positions in government. Kantakouzenos had reacted by proclaiming him basileus on the feast of St Demetrios and the empire was for once more in civil war. And unlike that between the two Andronikos fifteen years later this threatened to bring much darker passions to the surface. Kantakouzenos thanks to his earlier position and his reforms of the pronoia and taxation system over the past decade meant he could count upon the army and state apparatus in Thrace and Macedonia. But while his reforms had been inspired by the Lascarid ones he had seen at work in Sicily and the Morea there was a big difference between the two. Kantakouzenos and Andronikos had relied on the aristocracy. Their reform while restoring the functioning of pronoia and taxation, had relied on said aristocrats instead of the peasantry and the city communes Lascarid power had relied upon [2]. The lot of the lower classes had improved but that was incidental and a decade was hardly enough to remove the deeply rooted distrust for the aristocracy. Apokaukos, of humble origins himself, would deliberately try to play upon this and elicit the commoners support inciting mobs in Constantinople to attack the property of Kantakouzenos and his aristocratic supporters. Soon the new civil war would start to demostrate what future eras would call a class element...
[1] Three guesses on my opinions on hesychasm.
[2] Put differently Kantakouzenos been doing what the Ottomans would be doing a few decades down the road. Which may have similar macroscopic effects to what house Vatatzes is doing in you want to count taxation and the ability to raise armies but if you go below that to the details...
