Montessori for Social Justice was founded in 2013. After an impromptu gathering at the AMI International Montessori Congress members of the national Montessori community who attended began catalyzing relationships and resource sharing. 

In June 2014, the first “Montessori unconference” was held in St. Louis, MO and was attended by 35 people.

To date there have been 6 conferences with over 650 Montessorians attending each year.
