Final answer:
Marco Polo traveled by land to China, revealing rich trading possibilities with the East and influencing later European explorations and trade.
Step-by-step explanation:
The 13th-century Italian explorer Marco Polo journeyed extensively through the Mongol Empire, including traveling by land to China. In 1271, along with his father Niccolò and his uncle Maffeo, Marco Polo embarked on a voyage to the east, eventually reaching the court of Kublai Khan. Throughout their travels, the Polos were granted privileges such as free passage, lodgings, and horses thanks to a paiza, a golden tablet they possessed. Marco Polo's extensive travels and direct observations of the wealth and sophisticated products of China revealed the immense potential for trade with this distant civilization, highlighting the opportunities for luxury goods such as silk, spices, and porcelain. These revelations played a significant role in motivating later European exploration and trade expeditions, seeking to capitalize on the rich trade possibilities with the East.
