Globalisation is an increasingly broad, dynamic and complex phenomenon. Given the previous context and in an attempt to reduce its complexity, the underlying objective of this article is to contribute to a broader and more comprehensive discussion on globalisation in the light of the theme, democracy. We used a qualitative, exploratory and descriptive methodology, which focused on a theoretical analysis through a systematic literature review. The systematic review made it possible to synthesize the existing literature in order to provide a holistic view of the phenomenon. Therefore, our intention is to present a theoretical framework on the dimensions that contain the essence of globalisation in a postmodern version of democracy. The results suggest that there are no unambiguous metrics to measure the impact of globalisation. In that regard, it is essential to recognise globalisation as an opportunity and not as a threat, being aware of the underlying inequalities and the risks that they can pose to democratic states. Future studies can analyse the impact of the dimensions identified in this article and examine the differences within different countries and cultural contexts. The identification of opportunities that globalisation creates, as well as ways to mitigate possible inequalities and risks, can be useful in looking for new scientific and academic ventures.
