A merger or interaction between galaxy clusters is one of the most violent events in the universe. Therefore, an interacting cluster is an optimum laboratory to understand how galaxy properties are influenced by a violent change of the large-scale environment. Here, we present the observational evidence that bars in disk galaxies can form by cluster-cluster interaction and the bar formation is associated with star-formation enhancement.
