In recent years, the reach and influence of far-right ideologies have been extended through online communities with devastating effects in the real world. In this research, we examine how far-right online communities can be empowered by socio-political events that are significant to them. Using over 14 years of data extracted from an Australian national sub-forum of a global online white supremacist community, we investigate whether the group cohesion of the community is affected by local race riots. Our analysis shows that the online community, not only became more cohesive after the riots, but was also reinvigorated by highly active new members who joined during the week of the riots or soon after. These changes were maintained over the longer-term, highlighting pervasive ramifications of the local socio-political context for this white supremacist community. Pre-registered analyses of data extracted from other white supremacist online communities (in South Africa and the United Kingdom) show similar effects on some of the indicators of group cohesion, but of reduced magnitude, and not as enduring as the effects found in the context of the Australian far-right online community.

近年来，极权意识形态的影响力和影响力已通过在线社区得到扩展，在现实世界中产生了毁灭性影响。在这项研究中，我们研究了对他们意义重大的社会政治事件可以如何赋予最右翼的在线社区权力。利用从全球在线白人至上主义社区的澳大利亚国家子论坛中提取的14多年数据，我们调查了社区的群体凝聚力是否受到当地种族骚乱的影响。我们的分析表明，在线社区不仅在骚乱后变得更具凝聚力，而且在骚乱的一周内或之后不久也加入了活跃的新成员，使他们重新焕发了活力。这些变化是长期保持的，强调了这个白人至上主义社区对当地社会政治背景的普遍影响。对从其他白人至上主义在线社区（在南非和英国）提取的数据进行的预注册分析显示，它们对某些群体凝聚力指标具有相似的影响，但程度有所降低，并且不如上下文中的影响持久澳大利亚极右翼在线社区的成员。
