Guilds were organizations of skilled workers coming together to help and protect one another. 

Guild systems were created during the Middle Ages to protect skilled workers. Skilled laborers were typically dominated by men except for cases of widows. There are no real records of women being in guilds but many records of women working from home and taking care of children. Though guilds would come to the aid of widowed women, they were rarely allowed to join a guild.
