Final answer:
Islamic resurgence and globalization resistance summarize the major themes in Islam over the past 50 years.
Step-by-step explanation:
The major developments in Islam over the past 50 years can be summarized by the pair of words 'Islamic resurgence' and 'globalization resistance'.
In terms of Islamic resurgence, there has been a revival of religious practices and the growth of Islamic movements that seek to establish Islamic values in society. This can be seen in the rise of fundamentalism and the influence of religious institutions on politics and legal systems.
On the other hand, resistance to globalization has also been a major theme in the past 50 years. Many Muslim populations resent the economic and political effects of globalization and view it as a threat to their cultural and religious identity.
