History did not mention how coffee seeds left Ethiopia for Yemen specifically or through specific people. A number of sources stated that by the time it was traded in 575 AD, coffee trees had grown in Yemen coming from Ethiopia. A number of sources stated that by 1600 AD, it began to leave Yemen east and west on three routes.
The first method: through pilgrims:
It is said that an Indian pilgrim named Baba Budan took some coffee seeds in the sixteenth century AD or later, from Mecca while performing the Hajj, and then planted them in the Chandagiri Mountains area, which were later named the Baba Budangiri Hills; in honor of him as the first to introduce coffee to India.
The second method: via the port of /strong>
The second story tells that Dutch sailors took some arable coffee seeds to their colonies in Indonesia, then they spread to neighboring countries. In 1710 AD, the first coffee seedlings were sent to Holland. In 1714 AD, they arrived in France and were planted for the first time in a greenhouse. Then, in 1723 AD, they arrived in Martinique from France with explorers. It is said that they were watering it with their own drinking water because it was sent by the king and had to be preserved. In 1727 AD, they arrived in Brazil, which later became an icon of global coffee production.
The third method: Through the French:
Records show the third route of coffee's exit from Yemen to the world, via the French who tried to introduce coffee from Yemen to Bourbon Island (currently La Réunion) three times, in 1708, 1715 and 1718. Modern genetic studies have confirmed this, as only a few plants from the second batch and some from the third batch succeeded. Until the middle of the nineteenth century, the seedlings did not leave the island. In 1859, French missionaries transported seedlings to Zanzibar, from where they moved to southern Brazil.
