唐朝中后期皇帝女儿的婚姻困境与贵公子在社会上的选择
在唐朝中后期，虽然“皇帝的女儿不愁嫁”这一说法颇为普遍，但实际情况却是相反，“皇帝的女儿也愁嫁”，甚至有公主因找不到合适的夫婿而成为“剩女”。尽管时局动荡，国力衰弱，但作为最高统治者的皇帝依然会动用全部手段寻求解决之道，甚至下诏设立驸马选拔制度。但为什么即使如此，他们的女儿们仍旧难以找到合适伴侣呢？
通过考察历史资料，我们发现唐朝初期关于公主婚配的情况记载清晰明了，而到了中后期，这方面的记载则变得稀少。另一种现象是在这时期，一些公主选择出家成道，比如在唐文宗年间，有四位未婚公主选择了这个道路，她们分别是浔阳公主、平恩公主、邵阳公主和永安公 主。
在唐朝中后期，有九位以上的公主选择了出家的生活，其中还有几位终生未能结婚，最终郁郁而终。这些对婚事关注度极高的问题显然已经成为皇帝最头疼的事情之一。那究竟是什么原因导致了这种状况呢？对于唐朝君王而言，这种问题让人心生忧虑。
首先，由于身份特殊，public figures like princesses require a perfect match, which often leads to the pursuit of marrying into high-ranking families. However, this can be seen as an affront to traditional values and customs by these families, who may not accept such a union.
Furthermore, there is another reason that might contribute to the difficulty in finding suitable husbands for princesses. According to custom, after the death of their husband or father-in-law, the princess would need her husband or son-in-law to perform a "斩衰" mourning period of three years. This is considered one of the most severe forms of mourning in Chinese tradition and is typically reserved for sons burying their parents. The aristocratic families may view this as an unacceptable deviation from traditional norms and thus refuse any proposal.
These factors combined create significant challenges in finding suitable partners for Tang Dynasty princesses despite efforts made by royal authorities to ensure their marriage prospects are secure.
