Frise chronologique cm1 à imprimer sur la Première Guerre

Historical timeline infographic titled "World War I: Major Phases, 1914–1918" with a dominant HORIZONTAL timeline ribbon across a museum exhibition panel layout, designed for sharp readable educational print clarity. Feature 7 milestone events placed evenly along the ribbon, each with precise date, short heading in English, one-line caption in English, and a clear period-appropriate visual cue. Because this is a war timeline rather than an empire, structure the ribbon with neutral phase labels overlaid above it: "Outbreak" → "Stalemate" → "Global War" → "Turning Point" → "Collapse" → "Armistice". Milestones: 1) "28 June 1914" — heading "Sarajevo Assassination" — caption "The killing of Archduke Franz Ferdinand triggered the July Crisis." — visual cue: black mourning ribbon and pistol silhouette. 2) "28 July 1914" — heading "War Begins" — caption "Austria-Hungary declared war on Serbia, setting alliance systems in motion." — visual cue: sealed diplomatic letter and broken chain. 3) "5–12 September 1914" — heading "First Battle of the Marne" — caption "The German advance toward Paris was halted, opening trench warfare on the Western Front." — visual cue: trench line, field map, and officer whistle. 4) "25 April 1915" — heading "Gallipoli Landings" — caption "Allied forces opened a major campaign in the Ottoman straits with limited success." — visual cue: landing boat, coastline contour, and anchor. 5) "31 May–1 June 1916" — heading "Battle of Jutland" — caption "The largest naval clash of the war showed the strategic weight of sea power." — visual cue: dreadnought silhouette and compass rose. 6) "6 April 1917" — heading "United States Enters War" — caption "American entry strengthened the Allied war effort in men, industry, and finance." — visual cue: steamship, supply crate, and telegram sheet. 7) "11 November 1918" — heading "Armistice Signed" — caption "Fighting ended on the Western Front after the collapse of the Central Powers." — visual cue: folded document, laurel branch, and silent bugle. Include a small inset map labeled "Europe and the Main Fronts, 1914–1918" showing Western Front, Eastern Front, Gallipoli, and major sea zones with a subtle highlighted territorial reach element labeled "Central Powers and Allied Theaters". Add 3 key figures in small portrait medallions with dates and exact rendered names: "Woodrow Wilson (1856–1924)", "David Lloyd George (1863–1945)", "Paul von Hindenburg (1847–1934)". Since the user scope conflicts with the topic, do not force a single-reign framing; instead keep the chronology historically accurate and neutral. Visual style: museum exhibition panel, editorial historical illustration, textbook-grade clarity, period-appropriate imagery, vector-clean lines, elegant archival composition, clean iconography, engraved inset portraits, subtle paper texture, fine legend markers, crisp typography, no gore, no death photography, no propaganda tone. Color palette: ancient bronze, aged brass, deep navy, parchment beige, muted slate, soft ivory highlights. Overall mood: sober, scholarly, balanced, informative, and tasteful. Ensure all labels are large, high-contrast, and printable for classroom use. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render dates in Arabic numerals. Avoid graphic battlefield gore, no real death photos, no flags or symbols of hate movements. For contested historical narratives, present neutrally — no propaganda framing, no glorification of atrocities. Period-appropriate but tasteful.
