We study the history-dependent percolation in two dimensions, which evolves in generations from standard bond-percolation configurations through iteratively removing occupied bonds. Extensive simulations are performed for various generations on periodic square lattices up to side length $L=4096$... From finite-size scaling, we find that the model undergoes a continuous phase transition, which, for any finite number of generations, falls into the universality of standard 2D percolation. At the limit of infinite generation, we determine the correlation-length exponent $1/\nu=0.828(5)$ and the fractal dimension $d_{\rm f}=1.864\,4(7)$, which are not equal to $1/\nu=3/4$ and $d_{\rm f}=91/48$ for 2D percolation. Crossover phenomena between the two universalities are clearly observed. The transition in the infinite generation falls outside the standard percolation universality, and apparently differs from the discontinuous transition of history-dependent percolation on random networks. read more
