 ## History
 
-TODO: Write history
+The idea of standardizing maps in the web platform arose from discussions at a 
+W3C linking spatial data workshop in 2014. A second 
+online workshop focused on maps for the web was held in 2020, and from the latter,
+many detailed requirements for maps on the web were presented. The MapML 
+polyfill attempts to track and implement these (evolving) requirements, with the
+intent being to eventually fully specify and the requirements of web map
+users as an update to the HTML Living Standard, implemented by browsers.
