Let $G \leq \mathrm{Sym}(\Omega)$ be a primitive permutation group. A base for $G$ is a subset $B \subseteq \Omega$ such that the pointwise stabiliser $G_B=1$. In this talk, after outlining the history and uses of bases, I will describe some recent work towards two prominent problems in the area – namely the solution to Pyber’s conjecture and the classification of primitive groups with base size two.
