Chinese military general Cao Qin and his officers, of Mongol and Han descent, are fearful of being next on the Tianshun Emperor's purge-list of those who had aided his half-brother Jingtai's earlier succession during the 1449 Tumu Crisis.

In 1461, they stage a coup against the Tianshun Emperor.

After setting fire to the eastern and western gates of the Imperial City (which are doused by pouring rains during the day-long uprising), Cao Qin, betrayed by two Mongol officers, finds himself hemmed in on all sides by imperial forces, loses three of his own brothers in the fight, and instead of facing execution flees to his house and commits suicide by jumping down a well located within the walled compound of his urban Beijing home.

The rebellion marks the high point in political tension over allowing Mongols to be employed in the Ming military command structure.

Ming Chinese officials often compensate Mongol subordinates for military merits while at the same time strategically relocating their troops and families away from the capital.

Books begin to be printed that combine woodcut illustrations with a text set in movable type.

The German printer Albrecht Pfister of Bamberg is credited with being the first to do this; his edition of Ulrich Boner's "Der Edelstein," is widely accepted as the first illustrated book.

Pfister prints Der Edelstein's text, however, from movable type, then prints the illustrations separately on blank areas left on the pages.

The conflict between Ţepeş and Mehmed continues until 1461, when Mehmed asks the Prince to come to Constantinople and negotiate with him.

At the end of November 1461, Ţepeş writes to Mehmed that he cannot afford to pay him tribute, as his war against the Saxons of Transylvania has emptied his resources, and that he cannot leave Wallachia and risk having the Hungarian king take over his domains.

He further promises to send the Sultan plenty of gold when he can afford to and that he will go to Constantinople if the Sultan will send him a pasha to rule over Wallachia in his absence.

Meanwhile, the Sultan receives intelligence reports that reveal Ţepeş's alliance with Hungarian king Matthias Corvinus.

He dispatches the bey of Nicopolis, Hamza Pasha, to stage a diplomatic meeting with Vlad at Giurgiu, but with orders to ambush him there; and thereafter, take him to Constantinople.

Ţepeş, forewarned about the ambush, plans to set an ambush of his own.

Hamza brings with him one thousand cavalry and when passing through a narrow pass north of Giurgiu, Ţepeş launches a surprise-attack.

The Wallachians have the Turks surrounded and fire with their handgunners until the entire expeditionary force is killed.

Historians credit Ţepeş as one of the first European crusaders to use gunpowder in a "deadly artistic way."

The new prince fights bitterly against the Turks, and, because of his sadistic cruelty toward subjects and Turkish prisoners alike, becomes known as Vlad the Impaler (and, as Dracula—or son of the Devil—will become the source of the Dracula legend).

Vlad, who reportedly takes abnormal pleasure in inflicting torture and watching his victims writhe in agony, hates the Turks and defies the sultan by refusing to pay tribute.

In 1461, Ottoman commander Hamza Pasha tries to lure Vlad into a trap, but the Wallachian prince discovers the deception, captures Hamsa and his men, impales them on wooden stakes, and abandons them to their deaths.

The first Church of the Holy Apostles, also known as the Imperial Polyándreion (imperial cemetery), an Eastern Orthodox church in Constantinople, dates to the fourth century, though subsequent emperors have added to and improved on the space.

It is second in size and importance only to the Hagia Sophia among the great churches of the capital.

When Constantinople fell to the Ottomans in 1453, the Holy Apostles had briefly become the seat of the Ecumenical Patriarch of the Greek Orthodox Church.

Three years later the edifice, which was in a dilapidated state, had been abandoned by the Patriarch, and in 1461 it is demolished by the Ottomans to make way for the Fatih Mosque.

Abu Sa'id has conquered eastern Iran and most of Afghanistan by 1461, agreeing with Jahan Shah to divide Iran between them.
