Pompey disembarks at Pelusium upon arriving in Egypt, whereupon he is assassinated by order of King Ptolemy XIII.

Pompey the Great, defeated by Caesar, lands in Egypt and is treacherously killed on King Ptolemy XIII’s orders.
In 48 BC, Pompey the Great, fleeing defeat by Julius Caesar, landed at the Egyptian port of Pelusium. Hoping for asylum and political leverage, he sought the favor of King Ptolemy XIII. Fearing Caesar’s wrath and influenced by court intrigues, Ptolemy’s advisors ordered Pompey’s assassination. As Pompey disembarked, he was murdered by agents of the king and his severed head was sent to Alexandria. The grisly act was intended to curry favor with Caesar but instead horrified Roman sensibilities. Caesar, on his arrival, publicly repudiated the murder and arranged a dignified funeral for Pompey. Pompey’s death marked a dark turning point in the Roman civil wars and the end of a great general’s career.

The Brazilian Parliament passes a law that frees all children thereafter born to slaves, and all government-owned slaves.

In 1871, the Brazilian Parliament enacts the Law of Free Birth, freeing all children born to enslaved mothers and all government-owned slaves.
On September 28, 1871, the Brazilian Parliament passed the Law of Free Birth (Lei do Ventre Livre), a landmark decree that emancipated all children born to enslaved women from that day forward and immediately freed slaves owned by the government. While adult slavery persisted, this measure represented the first major legislative step toward ending the institution in Brazil. The law challenged plantation owners to adjust labor practices and contributed to growing abolitionist movements. It also laid the groundwork for the eventual abolition of slavery by the Golden Law in 1888. Today, this legislation is celebrated as an important milestone in Brazil's journey toward human rights and social justice.
