Peacekeeping and the Peacekept: Cease-Fire Episodes in Civil Wars (Fortna)Fortna 内战维和与停火维持数据集（Peacekeeping and the Peacekept）

Each row is one cease-fire / peace episode after a civil war (Doyle-Sambanis list), 156 episodes in total: 95 cease-fires from the post-Cold War sample (January 1989 to December 1999, coded by Fortna) and 61 earlier cease-fires from 1945-1988 used to establish the baseline difficulty of keeping peace. Peace is observed through December 31 2004. The raw Stata file stores spell periods: within-episode rows change when a peacekeeping mission deploys, changes mandate or leaves (192 rows for 156 cases). This registry collapses each episode into one row; mission variables show the highest peacekeeping type deployed during the episode (equivalent to the author's time-constant pkopC1).

For each episode the registry shows the country (original COW code plus ISO3), cease-fire and failure dates, the duration of peace, whether war resumed by end-2004, the war outcome (government victory, rebel victory, truce or settlement), and whether a peacekeeping operation was deployed and of which type (monitoring, interpositional, multidimensional, enforcement) and by whom. In 43 of the 156 episodes peacekeepers were present; war resumed after 84 episodes.

本登记册每一行对应内战之后的一个停火/和平阶段 episode（基于 Doyle-Sambanis 内战清单）。共 156 个 episode：95 个来自 1989 年 1 月至 1999 年 12 月之间的停火（后冷战主样本，由 Fortna 亲自编码），61 个为 1945–1988 年的较早停火，用于估计维持和平的基线难度。和平是否维持观察至2004 年 12 月 31 日。原始 Stata 文件按阶段切分：当维和任务部署、变更授权或撤离时同一 episode 会出现多行（192 行对应 156 个 episode）。本表将每个 episode 压缩为一行；维和变量取该阶段内部署的最高任务类型（与作者提供的时不变变量 pkopC1 等价，已在脚本中核验）。每行记录国家（保留原始 COW 代码并补充 ISO3）、停火日期与战争复发日期、和平持续时间、截至 2004 年底战争是否复发、战争结果（政府胜利、叛军胜利、休战或全面和解），以及是否有维和行动、任务类型（观察、隔离、多维、强制）与主导方。156 个 episode 中有 43 个在停火后部署过维和部队；84 个 episode 后战争再度爆发。
