It was manifested in greater religious piety and in a growing adoption of Islamic culture. One striking example of it is the increase in attendance at the "Hajj", the annual pilgrimage to Mecca, which grew from 90,000 in 1926 to 2 million in 1979. But the said increase in the number of pilgrims may also be attributed to other factors such as increase in populations, modern transportation facilities and to some extent the over all financial prosperity of the Muslims all over the world thus making the Pilgrimage affordable to more and more Muslim populations.
