What Wordpress hook fires first admin_init or admin_menu

php wordpress plugins activation

admin_menu seems to fire before admin_init, here's what happens:

admin_menu fires in wp-admin/includes/menu.php on line 149
which is included at the end of wp-admin/menu.php on line 255
which is included in wp-admin/admin.php on line 115
after which admin_init fires in that same file on line 145
