what will happen to illegal migrants if crusades start again in europe

The most likely answer is: nothing like a “crusade” would create a lawful, Europe-wide rule for “illegal migrants”; in a real conflict or political upheaval, the outcome would vary by country, but under current EU policy irregular migrants are screened, processed, and—if they have no right to stay—returned. EU policy already says those who cross illegally may be held in border procedures, recorded in the Eurodac system, and then returned if their claims are rejected.

What is realistic

A modern “crusade” is not a legal category in Europe, so governments would not automatically treat migrants under some medieval-style rule. Any response would depend on emergency laws, border security, asylum law, and human-rights obligations in each country.

Likely outcomes

• Increased border controls and checks.
• Faster screening and processing at borders.
• More detentions or alternatives to detention for people not allowed to stay.
• More returns or deportations for rejected cases.
• Possible disruption in transit routes and asylum systems if there were wider conflict.

Important reality check

The term “crusades” is historical and refers to medieval military expeditions, not a modern European policy framework. In today’s Europe, the strongest documented trend is stricter irregular-migration enforcement and return rules, not religious war.

Bottom line

If you mean a serious political or military conflict in Europe, illegal migrants would most likely face tighter controls, slower or faster asylum processing depending on the country, and more removals for people without legal status. If you mean this as a hypothetical, the exact outcome would depend on the specific governments, laws, and security situation in each state.
