2015 seems to be the year of Caitlyn Jenner.

Since publicly coming out to Diane Sawyer — and the rest of America — in an emotional interview back in April, Caitlyn has only continued to be a mainstay in the headlines: From her iconic Vanity Fair cover in June to her incredibly moving speech at the 2015 ESPY Awards, Caitlyn has become more than just a woman who's trying to live her life: she's a powerful and important new voice for the transgender community, shedding light on issues that have never been more widely addressed by the public.

Along with her activism, Caitlyn has also had an epic personal journey, bravely deciding to share every step of her transition thus far, as captured in her ongoing docu-series, I Am Cait. We've gathered together Caitlyn's key moments through 2015 and chronicled them in the gallery above for a look back Caitlyn Jenner's time in the spotlight.
