Final answer:
Regimes become more repressive through severe measures like martial law, propaganda, and strict control over society, often reacting to perceived threats of dissent and aiming to align the populace with the state's goals. Enhanced information sharing in the 21st century has changed the dynamics of repression and resistance, leading to immediate and organized responses globally.
Step-by-step explanation:
The regime became more repressive by implementing severe measures to eliminate dissent and by actively engaging the population in the state's goals using propaganda and glorification of its leaders. Measures such as martial law, increased control by conservative and military forces, and the repression of political activists, including disappearances, were common. Examples of increased repression can be found in Syria under President Bashar al-Assad, the military junta in Myanmar, and the tight control of North Korean society under Kim Jong Il. These measures often include strict surveillance, suppression of freedoms, and harsh penalties for opposition, showing how threatening dissent was perceived by these governments.
In the 21st century, the dynamics of repression and the fight against it have evolved due to the rapid dissemination of information through the internet. Oppressed populations are now better organized and supported by global solidarity movements, making the response to repression more immediate compared to historical uprisings which simmered for decades or centuries.
