2019 is a year of deep uncertainty as we face unique challenges, threats, and opportunities. New technologies are changing the ways we communicate and connect, how we live and work, and the balance of power and wealth. New movements on the political left and right point to different futures we might share together or the ways we might come apart. On the Nines, a public history project, invites students, teachers, and the general public to critically revisit moments in the past when the world stood at a crossroads. Focussing on events that happened in years ending in “9,” from the completion of the first transcontinental railroad in 1869 to the stock market crash of 1929, to Stonewall in 1969 and Seattle in 1999, On the Nines will offer fresh insights from a team of young scholars on moments where the future hung in the balance. Our multimedia content is aimed at all learning styles, from carefully-researched articles to curated exhibits and podcasts. Join us as we reflect back “On the Nines” through a yearlong investigation of the moments, ideas, and people who shaped our world.
