This article introduces CShapes 2.0, a GIS dataset that maps the borders of states and dependent territories from 1886 through 2019. Our dataset builds on the previous CShapes dataset and improves it in two ways. First, it extends temporal coverage from 1946 back to the year 1886, which followed the Berlin Conference on the partition of Africa. Second, the new dataset is no longer limited to independent states, but also maps the borders of colonies and other dependencies, thereby providing near complete global coverage of political units throughout recent history. This article explains the coding procedure, provides a preview of the dataset and presents three illustrative applications.

本文介绍了CShapes 2.0，这是一个GIS数据集，可绘制1886年至2019年的州和附属领土的边界。我们的数据集建立在以前的CShapes数据集的基础上，并通过两种方式进行了改进。首先，它把时间范围从1946年扩展到1886年，随后是关于非洲分区的柏林会议。其次，新数据集不再局限于独立国家，而是绘制了殖民地边界和其他依附关系，从而在近期历史上几乎完全覆盖了政治单位的全球范围。本文介绍了编码过程，提供了数据集的预览，并提出了三个说明性的应用程序。
