Spaniard vs. Spaniard ... the Fight for Peru
Local Inca rebellions have been growing as the Pizarro brothers consolidate their control over the lands granted to them by the Emperor. Don Diego de Almagro has returned from surveying the lesser lands to the south that the Emperor granted him, including present day Chile. Don Diego is quite rich but the Pizarro brothers are getting filthy rich. That grates on him. There is a question of who owns the city of Cuzco so Don Diego takes the city. The stage is set for a battle of Spaniard verses Spaniard at Las Salinas, a short distance from Cuzco. Many of the Incas join the side of Don Diego hoping to free themselves from the Pizarros but the Pizarro Brothers win decisively. They enter Cuzco unopposed. Don Diego is executed by garroting despite his pleas to spare his life. This will be the last major opposition to the brothers as Inca opposition collapses.   
The Holy League is Wholly Ineffective
The Christians have been fighting the Ottoman Turks on several fronts and this has forced complex alliances that would never form naturally. In Italy, the Venetians have joined forces with Spain, Genoa, the Knights Hospitaller in Malta and the Papal States under Pope Paul the 3rd to form the Holy League. They will join in battle against Barbarossa in the Ionian Sea near Preveza. In their first encounter the Ottoman Turks take heavy casualties but lose no ships while the Holy League loses 10 ships. A second strike is in order, but the Genoans are the historic enemies of the Venetians. The Genoans sail away, figuring they have done enough and frankly the commander personally owns several of the ships and will not risk them further. The Holy League is no more. Barbarossa will return next year to mop up the remaining Christian outposts along the Ionian and Aegean seas.   
John Calvin Expelled from Geneva... Google Guy Expelled from the Revolution *
John Calvin had never meant to go to Geneva. He was originally going to Strasbourg but because of the war between the Holy Roman Emperor and the King of France, he took a side trip and ended up in Geneva. It was just for a night, but he was convinced by a friend to stay and preach there. He is called a pastor but there is no record of his taking vows at this time. His training is as a lawyer, so this preacher/lawyer has been backing "articles" or laws to suppress Catholic practice. Altars are smashed and chaos reigns so that even though the Geneva council is Protestant, they give the boot to several leaders of the movement including John Calvin. He will continue his trip to Strasbourg but he will return to Geneva one day and stay for the rest of his life.

"Militarily, Hernando Pizarro's stunning victory showed that a disciplined army could be moved effectively over the vast American distances, that infantrymen armed with cumbersome firearms could decide the day, and that Indian auxiliaries were unreliable. Politically, the victory undermined the confidence necessary for a concerted native effort against the Spaniards, and from that point on Indian fighting, however desperate, would become a kind of Spanish mopping up operation.".

They needed to determine in which portion the city of Cuzco was located. However, Almagro's troops quickly took the city and imprisoned the Pizarro brothers, Hernando and Gonzalo, on the night of 8 April 1537.”

There was to be a children's catechism, which he drew up; it ranks among his best writings. The city now broke into 'jurants' and 'nonjurors' for many would not swear to the 'articles'; indeed, they never were completely accepted.”
