The Black Death, also known as the bubonic plague, first spread across Europe from Asia through the trade routes. It arrived in Italy in 1347 and quickly spread to other European countries such as France, Spain, and England. The disease spread primarily through flea bites from infected rodents such as rats, which were prevalent in urban areas. It is believed that the movement of infected individuals and animals also contributed to the spread of the disease. Overall, the Black Death spread from the east (Asia) to the west (Europe) during the 14th century.
