During World War II, AMORC underwent a dramatic period of growth. After the war ended AMORC was able to lend support to its European sister organizations. Eventually many of those came under the administration of AMORC's leadership in San Jose. 2009, the centennial year of H. Spencer Lewis's initiation in Toulouse, saw growth in membership in the English Grand Lodge for the Americas and very active participation in on-line activities including Facebook, Twitter, online discussion groups, a social networking site, podcasts and Rosicrucian TV on YouTube. Rosicrucian Park in San Jose received many improvements as well, including the completion of accessibility upgrades to the museum, planetarium and grounds, and the installation of sustainable native plant gardens.
