The regent Kaahumanu , ruling in the name of her young charge , Kamehameha III , seized the opportunity and followed many of the strictures favored by the Calvinist Congregationalists , who were modernizing the country through the establishment of schools and the printing of books in the Hawaiian language ( which they formulated in a written form for the first time ) .
There was never anyone by the name of Kaahumanu in charge in Hawaii .
