A craft or trade is a pastime or a profession that requires particular skills and knowledge of skilled work. In a historical sense, particularly the Middle Ages and earlier, the term is usually applied to people occupied in small-scale production of goods, or their maintenance, for example by tinkers. The traditional terms and craftswoman are nowadays often replaced by artisan and rarely by craftsperson (craftspeople).
The beginning of crafts in areas like the Ottoman Empire involved the governing bodies requiring members of the city who were skilled at creating goods to open shops in the center of town. These people slowly stopped acting as subsistence farmers (who created goods in their own homes to trade with neighbors) and began to represent what we think of a "craftsman" today.
Historically, craftsmen tended to concentrate in urban centers and formed guilds. The skill required by their professions is and the need to be permanently involved in the exchange of goods also demanded a generally higher level of education, and craftsmen were usually in a more privileged position than the peasantry in societal hierarchy. The households of craftsmen were not as self-sufficient as those of people engaged in agricultural work and therefore had to rely on the exchange of goods.
Once an apprentice of a craft had finished his apprenticeship, he would become a journeyman searching for a place to set up his own shop and make a living. After he set up his own shop, he could then call himself a master of his craft.
