History and Strategic Affairs Society




RI’s History and Strategic Affairs Society (HSTA) is a student-run Model United Nations (MUN) club. Through the medium of MUN, we give members a platform to grow into charismatic and confident speakers.

HSTA organises the annual Raffles Model United Nations (RMUN). RMUN 2024 will be its 32nd iteration, making it the one of the oldest Model UN conferences in Singapore. Drawing about 300 secondary and JC students each year, members contribute through carrying out such tasks as writing study guides, preparing for and taking on the role of Council Chairs, and conceptualising and acting as relevant characters at Council sessions to deepen delegate discussion and thought.  

HSTA’s weekly training sessions also seek to develop other skills in members, who are encouraged to think on their feet through MUN simulations and learn and share about current affairs through presentations. The aim is to nurture outspoken yet eloquent members passionate about global issues and able to articulate their thoughts clearly and confidently.
